Hi everybody!
I'm looking to acquire knowledge in IP telephony and VoIP. I'm testing some configuration back to back and I have some problems with a T1 CAS link.
Here is my situation:
On each side, I have two analog phones connected to a 2811 router. The routers are connected by a T1 CAS link (with a T1 crossover cable).
I can call a local number, but when I try to reach the remote phone, I get only one ring tone in the local phone, but no ring on the remote phone.
I tried on a T1-PRI connection and I have not problem.
The problem is that I do not do the commands "debug cas" on my router (the command is not present)
There is my configuration:
