Recording Phone Calls
Automatic Call Recording
By default, CallReplay will automatically record all calls for the licensed phones, without any human intervention.
Demand Recording
Alternatively, you have the option to only record calls at human request, by easily selecting "Record This Call" from an IP Phone Service or Web Browser. The selected call will be recorded from the very beginning of it, even if the softkey was pressed in the middle of the call. However, there is an option to record the call since requested.
What calls can be recorded
CallReplay will record incoming and outgoing calls going through Cisco CM, IPTrade Turrets, Mitel MCDs and SIP VoIP PBXs. All calls will be recorded automatically, without user intervention. Held/resumed, transferred and parked calls will also be recorded.
Supported PBXs
- Cisco: CallManager versions 3.0 up to 12.5, CallManager Express 3.3 and upwards are supported.
- IPTrade Turrets
- MiTel MCD 3300
- NEC SV8100, NEC SV8300
- All SIP based PBX such as Vonage, Broadcom, etc
Supported Codecs
CallReplay uses an array of codecs (G.711 A and U, G.722, G.729 A and B, Opus) to ensure that all calls are recorded and using a minimum possible of disk space and with the highest quality possible.
Cisco
Forked/Active (SPANless) Recording using built-in bridges
Starting from version 6, CallReplay can record Cisco phones without using any kind of port mirroring on the switch. Only Cisco phones with built-in bridges can be recorded (like 7941 and newer). More information. Version 8.0 introduced IPTrade active recording. Mitel MCDs are always actively recorded.
Passive network sniffing
CallReplay does not use any CTI ports to the PBX, which cost extra and may place additional load on the PBX. Instead, it uses passive network sniffing, which is completely undetectable and places zero load on the CM. Below is a call flow diagram in a internal network for recording external calls. Each call has 2 components, RTP (green) and Call Control (blue). The flow of each component is represented in the diagram. Note: Internal traffic (represented with red) will not be recorded unless CallReplay is plugged in the same switch as the phones to be recorded.
Hybrid CTI-SPAN recording
Added in version 7, CallReplay can record Cisco phones using JTAPI for the signalling and SPAN for the RTP of gateways. This is especially useful when recording old phones or devices without forked recording support, in complicated network environments.
