3725 Router running 12.2(13)T with ISDN PRI connection. Call comes inbound to IPPhone. User picks up. IPPhone user says hello, hello. PSTN caller hears only second hello. So ther2 is maybe a 2 second delay. Here is my voice-port config:
voice-port 2/0:23
output attenuation -3
echo-cancel coverage 32
echo-cancel suppressor
non-linear threshold -20
no comfort-noise
timeouts interdigit 3
Any help would be great.
