4.9 Tracing
2N VoiceBlue MAX
®
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
function should be activated before tracing. Any Telnet–
Write communication into file
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.
