We are using a cisco 2911 router as mgcp gateway with one T1 and 4 fxs port. We have an issue of fxs port. Incoming call to the analog phone through fxs port is ok but for outgoing it doesn't work. We set the same CSS as normal ip phone. There is no issue of ip phone but the analog phone cannot call out. I have ran debug isdn q931 and there is nothing when using the analog phone to make outgoing call. Any expert has idea of the issue?
Thanks & regards,
So from external (pstn) and internal (ip phone) to the analog phone work well.
From the analog to the ip phone you get the vm of the ip phone.
From the analog to external you get a busy.
And you don't See anything in the debug on the gateway??
Even Not at the working part?
