I have 2 cisco routers, one with a dual-fxs card, the other with a dual-fxo card.
I can successfully call from the PBX to the cisco with the fxo (main router) and then call to the fxs points.
But in the reverse order, if i try to call from the fxs router(remote router) to the fxo router, it calls, the fxo answers, i dial a pbx extension and it rings… the extension answers, and i can hear the voice (from the pbx to the fxs), but they can’t hear anything (the voice from the fxs to the pbx)
My configuration in the main router:
voice-port 0/0/0
cptone MX
!
voice-port 0/0/1
!
!
mgcp profile default
!
dial-peer cor custom
!
!
!
dial-peer voice 1 pots
destination-pattern 100
port 0/0/0
!
dial-peer voice 2 voip
incoming called-number .
destination-pattern 20.
session target ipv4:192.168.0.99
dtmf-relay h245-signalMy configuration in the remote:
call rsvp-sync

voice-port 1/0/0
cptone MX

voice-port 1/0/1

destination-pattern 10.
session target ipv4:192.168.0.100(i just can’t understand , maybe it’s a silly thing i can’t see)
Thanks in advance for any guidance.

Your issue is the nat do you have firewal or a router between the voip
I am facing only this issue with the nat
Check for following:
1. Ensure that your router does not have the no ip routing global configuration command.
2. Issue the voice rtp send-recv in global configuration command
3. Issue debug cch323 rtp command and the debug voip rtp command to identify the root cause.
Need more help, send email at ciscovoipresource@gmail.com
