[Asterisk-Users] RTP path with Cisco CCM

[Patrick Zwahlen]

Thx Scott,

However, and from what I can read, chan_sccp is not really meant for
server-to-server trunks, yet...

Am I wrong ?

Patrick,
I would try to get * to talk SCCP(Skinny).  The Cisco phones are either
going to talk SIP or SCCP but I'm not aware that they will talk both.

Take a look at http://chan-sccp.sourceforge.net/

Good Luck
Scott
