Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Embodiment one

FIG. 1 is a flowchart of a call recording method provided by Embodiment 1 of the present invention. The method provided in this embodiment is applicable to the case of recording a call terminal in a telephone network. The method can be executed by a recording server, and the recording server is usually implemented by hardware and/or software, as shown in FIG. 1 , the present invention The method of an embodiment may include:

S110. Acquire signaling from the mirrored switch.

The current PBX is the telephone network system used within the company. In the system established through the PBX, a PBX usually has multiple ports, which can connect a corresponding number of user phones; Taking PBX (IP Private Branch exchange, referred to as: IP-PBX) as an example, the call recording method provided by the embodiment of the present invention is described. The IP-PBX is physically connected to the mirror switch (Switch) and the recording server respectively. Specifically, the recording server obtains the signaling of the calling terminal from the mirroring port of the Switch. It should be noted that, in this embodiment, during a call in the telephone network system, the recording server obtains the signaling from the mirroring port of the Switch in real time. The acquired signaling may be encrypted signaling or unencrypted signaling.

S120. Receive a recording instruction sent by the PBX, where the recording instruction includes the number of the call terminal.

In this embodiment, the recording server may also receive a recording instruction sent by the IP-PBX during a call in the telephone network system, and the recording instruction received by the recording server includes the number of the call terminal communicating through the PBX. The recording instruction sent by the PBX is used to instruct the recording server to record the media stream of the calling terminal. It should be noted that the PBX can send the numbers of both parties in the call to the recording server through the recording command, instructing the recording server to record the media stream between the two parties in the call; it can also send only the number of one of the two parties in the call to the recording server. Instruct the recording server to record the media stream received and sent by the call terminal corresponding to the number.

It should be noted that in this embodiment, the IP-PBX can start the recording function by selecting the call terminal, and the recording command sent can usually be selected to start the recording function by selecting a specific function button on the call terminal, or by The telephone network system judges the recording authority of the call terminal, and automatically activates the recording function when the user with the recording authority makes a call.

S130. Analyze the signaling, and determine a recording mode according to the number in the recording instruction and a result of analyzing the signaling. The determined recording mode is specifically mirror recording or conference recording.

In this embodiment, the recording server can obtain the analysis result by analyzing the signaling obtained from the Switch. As mentioned above, the signaling can be encrypted signaling or unencrypted signaling; specifically, if the signaling is not encrypted, Then the recording server can obtain the number in the signaling by analyzing the signaling, and the IP address and media port corresponding to the number, and the number is the calling number and/or called number in the signaling; if the signaling For encrypted signaling, the recording server cannot analyze the signaling, that is, it cannot obtain the number in the signaling, as well as the IP address and media port corresponding to the number; The results are different. Further, the results obtained after analyzing different types of signaling are usually used to match the number in the recording command. The recording server determines the recording method according to the matching result. The recording method is specifically mirror recording or Recording at the venue.

In the specific implementation of this embodiment, after the recording server determines the recording mode, it can also send a notification message to the IP-PBX, which is used to notify the IP-PBX of the determined recording mode. After receiving the notification message, the IP-PBX can also send a notification message to the recording server. Return the corresponding confirmation message. In actual use, the command and message interaction between IP-PBX and recording server is sent and received through the direct connection port, and the recording server obtains signaling and media streams through the mirror port of Switch.

Optionally, S130 of this embodiment may include: analyzing the signaling to obtain the number in the signaling, and the IP address and media port corresponding to the number, and storing the result of the analysis in the recording server; The number is matched with the analysis result stored in the recording server. When the analysis result matches the number in the recording instruction, the recording method is determined according to the IP address corresponding to the number and the media stream transmitted through the media port.

In this embodiment, the signaling is analyzed, and when the number in the recording command can be matched in the result of the analysis, the recording server judges that the signaling obtained from the Switch is not encrypted, so it can be obtained from the mirror port of the Switch through The IP address corresponding to the number and the media stream transmitted by the media port, but the determination of the recording method of the media stream transmitted through the IP address and media port corresponding to the number needs to be further determined according to the specific conditions of the media stream, usually The recording method can be determined according to whether the transmission mode of the media stream transmitted through the IP address and media port corresponding to the number is transmitted through the Switch, or point-to-point transmission between call terminals, and whether the media stream transmitted through the Switch is encrypted.

In the specific implementation of this embodiment, since the number in the recording instruction can be matched in the analysis result of the signaling, the recording server can specifically obtain the IP address and media port corresponding to the number in the recording instruction from the matching result, Thus, the recording mode can be determined according to the IP address corresponding to the number and the media stream transmitted through the media port; for example, FIG. 2 is a schematic diagram of a call recording scenario provided in an embodiment of the present invention. The server can identify the media stream transmitted through the IP address and media port from the media stream obtained from the Switch, and analyze the identified media stream to determine whether the media stream is encrypted. In the scenario shown in Figure 2, it can be specifically determined that If the media stream is not encrypted, the recording server will determine the recording method as mirror recording. In the recording scenario shown in Figure 2, both signaling and media stream information can pass through the IP-PBX, that is, the call recording scenario of this embodiment is intra-office An external call, and the signaling in the call may be, for example, Session Initiation Protocol (SIP) signaling, and the media stream may be, for example, Real-time Transport Protocol (RTP) media stream , therefore, the manner in which the recording server records the media stream of the call terminal is specifically to record the media stream transmitted through the IP address and media port among the media streams obtained from the Switch. It should be noted that in this embodiment, the judgment of whether the media stream transmitted through the IP address and media port is encrypted can also be obtained by analyzing the SIP signaling to obtain the indication information in the signaling. When the media stream of the IP address and media port is not encrypted, the recording server determines the recording mode as mirror recording.

For another example, FIG. 3 is a schematic diagram of another call recording scenario provided in the embodiment of the present invention. The scenario shown in FIG. 3 corresponds to the unrecognized IP address and The media stream transmitted by the media port, and the recording scene when the media stream transmitted through the IP address and media port is identified from the media stream obtained from the Switch, and the identified media stream is determined to be encrypted. In all scenarios, the recording server determines the recording mode as venue recording.

It should be noted that, in the scenario shown in Figure 3, on the one hand, the recording server learns that the media stream transmitted through the IP address and media port has been encrypted, and may analyze the SIP signaling to obtain the indication information in the signaling, The indication information indicates that the media stream passing through the IP address and the media port is in encryption mode, and the recording server may also determine that the media stream is in encryption mode according to the noise signal obtained from the Switch. In this call scenario, the media stream can be, for example, For secure real-time transport protocol (Secure Real-time Transport Protocol, referred to as: SRTP) media stream, although the recording server can obtain the SRTP media stream transmitted through the IP address and media port from the mirror port of the Switch, but cannot The SRTP media stream is decrypted, so the recording method is determined as venue recording; on the other hand, for the IP address and media port corresponding to the number in the recording command, the recording server fails to identify the IP address through the media stream obtained from the Switch. and the media stream of the media port, indicating that the media stream of the call terminal does not pass through the Switch, that is to say, the point-to-point intercommunication between the call terminals does not pass through the IP-PBX, that is, the call scenario is an internal call. In this call scenario, the signaling is the same It can be SIP signaling, but it does not limit whether the media stream is encrypted. For example, the media stream can be RTP media stream or SRTP media stream. In order to realize the recording of internal calls, the recording server can also determine the recording mode as conference recording.

S140. Record the media stream of the calling terminal according to the determined recording manner.

In this embodiment, the recording server analyzes the acquired signaling, matches the number in the received recording instruction with the analysis result of the signaling, and determines the signaling type suitable for the call scene after determining the signaling type. Recording method, specifically according to the determined recording method, that is, mirror recording or venue recording to record the media stream of the call terminal.

In this embodiment, the above-mentioned recording server can match the number in the recording instruction in the analysis result of the signaling as an example for illustration. Under the matching result, the recording server judges that the signaling is not encrypted. In the specific implementation , the recording server performs mirror recording on the unencrypted media stream. When the recording server cannot use mirror recording in other call scenarios mentioned above, the recording method is confirmed as venue recording, that is, the call recording method provided in this embodiment. In the recording server It is determined that mirror recording is used as much as possible in the scene where the conditions are suitable. When mirror recording cannot be applied to the current call scene, site recording is selected. Therefore, the method of this embodiment reduces the number of times of using site recording as much as possible, to a certain extent The resource consumption of the IP-PBX is reduced, and the resource waste of the recording system is correspondingly reduced.

In the call recording method provided in this embodiment, the recording server analyzes the signaling obtained from the Switch, and determines the recording mode as mirror recording or venue according to the number in the recording instruction received from the PBX and the result of signaling analysis Recording, which enables the recording server to record the media stream of the call terminal according to the determined recording method. This embodiment specifically selects a recording method suitable for the current call scene based on the judgment of the signaling type and the specific conditions of the media stream. It ensures that in the process of selecting the recording method, mirror recording is adopted as much as possible, that is, the number of recordings in the venue is reduced as much as possible, and the recording method in the prior art needs to use PBX resources as the venue during the recording process. ; To a certain extent, the resource consumption of the PBX is reduced, and the resource consumption of the recording system is correspondingly reduced.

Further, in another possible implementation of this embodiment, S130 may include: analyzing the signaling to obtain the number in the signaling, and the IP address and media port corresponding to the number, and storing the result of the analysis In the recording server; the number in the recording instruction is matched with the analysis result stored in the recording server, and if the number in the recording instruction is not matched in the analysis result, the recording mode is determined as conference recording.

Fig. 4 is a schematic diagram of another call recording scenario provided in the embodiment of the present invention. In the call scene of this embodiment, the signaling is analyzed, and when the analysis result cannot match the number in the recording instruction, The recording server judges that the signaling obtained from the Switch is an encrypted signaling, for example, it can be an encrypted SIP signaling, that is, after the recording server receives the recording instruction sent by the IP-PBX, it cannot use the number in the recording instruction from The parsing result stored by the recording server matches the IP address and media port corresponding to the number. Therefore, the recording server can only obtain the media stream of the call terminal through the recording at the venue.

In specific implementation, in the call recording scenarios shown in Figure 3 and Figure 4, venue recording is used to record the media stream of the call terminal. On the basis of the embodiment shown in Figure 1, S140 may include: sending to the IP-PBX A site recording instruction, so that the IP-PBX creates a site and adds the call terminal and the recording server to the site; and then records the media stream of the call terminal in the site. It should be noted that this embodiment can be a call in an external office or an internal call on a telephone network, and there is no restriction on whether the media stream obtained from the Switch is encrypted; generally, the calling terminal can include the calling terminal and the The called terminal, after the IP-PBX creates a call site, can also decrypt the encrypted media stream information received from the calling terminal and the called terminal respectively, and send it to the recording server after mixing, so that the The recording server obtains the decrypted media stream information from the conference site, as shown in Figure 3 and Figure 4, after the conference site is established, the recording server does not need to obtain the media stream transmitted through the IP address and media port through the mirror port of the Switch, but in The site directly obtains the media stream from the media port of the IP-PBX.
