VoiceBlue Next allows for operation tracing (VoIP, SIP, GSM). Tracing is
accessible in one session only at a time, the other tracing requests are rejected with
BUSY. With regard to a rather extensive volume of data, we recommend that the
Write communication into file function should be activated before tracing. Any
Telnet-supporting terminal (HyperTerminal, Putty, etc.) can be used.
Tip
You are advised to synchronise your GSM gateway with the SIP Proxy, or a
PC before tracing.
