I have a 2621 router running 12.1(5)YD5 with 2 FXO ports, outbound calls go out the FXO and my call manager is connected via the WAN created by a PIX-PIX VPN. When my WAN goes down, the phones go into fallback mode but do not recieve inbound calls and when I make an outbound call, I can hear the person I call but they can't hear me. My router config is:
ip source-address 172.16.2.253 port 2000 strict-match
dialplan-pattern 1 8067622... extension-length 3
and access-list is:
access-list 100 deny tcp any eq 2000 any eq 2000
access-list 100 permit ip any any
can anyone tell me what is wrong?
