I've got a 2811 with a VIC2-2FXS card. 1 port is connected to a ITS Pantel 1 button doorphone.
The doorphone is programmed to dial a 4 digit extension.
The router has a voip dialpeer to point to the callmanager (version 7).
The ipphone rings but as soon as the call is answered, the call is disconnected.
If I connect a normal analog line to the same FXS port, and dial the 4 digit extension everything is working fine.
An incoming call to the doorphone is also working fine. The doorphone automatically picks up
and the call is established.
When I use a ATA, all is working fine as well.
Any idea on how to solve this? WHich debug commands can I run to try and determine the cause?
Thanks in advance,
