SIP trunk calls are mirrored via a network switch so that a copy of the audio data is sent to a port connected to a second network card on the Echo call recording server. This data will be monitored by Echo and record new calls as they happen.
There are two possible ways to record SCCP calls. To record both internal and external calls the port that the SCCP phone is plugged into needs to be mirrored to a second network card on the Echo call recording server. If only external calls are required then you can mirror the phone systems network port(s).
To be able to record ISDN (and analogue) calls you will need additional hardware. The hardware required is deternined by the type of lines being recorded and the number of lines. Typically for sites with less than 30 PRI channels, we'd supply a USB box. This receives a copy of the ISDN traffic through a splitter and records the calls on a server connected via its USB cable.
Absolutely! As long as the virtual network adaptor supports promiscuous mode, and the virtual network switch supports port mirroring then there is no reason why you cannot record on a virtual server. If the network switch is physical then the second physical network card of the virtual machine host needs to support promiscuous mode to be able to pass the mirrored traffic to the virtual machine guest.
Call masking is included as standard with our call recording solutions via an open API. This means that you can integrate it with your CRM system, as a separate feature. Users will be able to initiate masking, and when to start recording again, so only the part you want cut off is masked.
Yes it is. Within either TIM Plus or TIM Enterprise you need to enable the "Do not record" property on the user, and then any calls they are involved in will not be recorded.

If you only want to record a few handsets then the best way would be to mirror each of the handsets you want to record to a dedicated port on the network switch which will be connected to the recording server. This will record all voice calls on those specific handsets.

At the moment we support G7.11 aLaw/uLaw so they would need to be set to that codec. These recordings would then be associated with their respective call record within TIM Plus/Enterprise so all playback would be done directly through the web interface. You can then apply the usual reporting filters to the reports to find specific numbers/people.

If you want to record a lot of extensions then setting up each extension may be a little time consuming, so you could mirror the hub and GW directly. Initially this would record everything, but you can set extensions within TIM Plus/Enterprise to "Do not record" if you don't want their audio saved.
