Passive VoIP Recording Checklist

Before Voice Over Internet Protocol (VoIP) extension recording can be offered, a site survey at the customer site

must be performed to determine the possibilities. The following owchart will help you to determine if and when VoIP

extension recording is possible. The step-by-step diagram poses questions for you to answer in order to understand

the VoIP extension recording. When VoIP extension recording is not possible, the alternative could be trunk side

recording.

VoIP communication

VoIP is the new architecture that provides some

unique challenges for recording solutions. The

functional components are distributed around

IP networks that are unlike traditional PBX en-

vironments, in such that there is no centralized

point to capture the audio such as at a MDF in

traditional technology.

Codecs

Versadial VSLogger supports following au-

dio codecs G.711, G.729A, G722 (wideband

Cisco). The G.729a, codec needs additional

licenses. If the codec is not listed at this support

section, contact Versadial for availability.

Using a compression codec (G729 ) requires

extra processing power and can reduce the

maximum number of recorded channels per

recording server.

Encryption

Versadial VSLogger doesn’t support passive

recording of encrypted VoIP. The only option is

to turn encryption off. There are several en-

cryption possibilities like IP-SEC, VoIP audio

encryption, VoIP signaling encryption. Some

switches encrypt VoIP signaling without the

option to turn encryption off, then recording of

audio is still possible, but some of the call infor-

mation (dialed number etc.) could be lost.
