Hello Everybody


I have this call flow:


PSTN (FXO) --> TCL File | Gw (H323) --> CUCM --> IP Phone


I have next Dial-peer in Gateway whith 9T pattern:

dial-peer voice 101 voip
 translation-profile outgoing test
 destination-pattern .T
 session target ipv4:
 dtmf-relay h245-alphanumeric
 no vad


Please your help to reduce the interdigit timeout value because 10 seconds are too long.

I have tried this:


In the voice port:

voice-port 0/1/0
 timeouts interdigit 2


Under Telephony Service:

 timeouts interdigit 2


Under H323:

  h225 timeout t302 2


No option worked. Some suggestion??

Thanks in advance!

Hello there. I just ran into the same issue on 3945E running 154-3.M4 code. I have opened a Cisco case, but not getting anywhere with it yet.

Thank you for your note. I got my issue resolved. There were not a TCL script involved. I was testing a SRST setup and was trying to change interdigit timeout with  timeouts interdigit command under voice-port with no affect. The actual command that changes it for eFXS ports (phones registered to SRST gateway) is timeouts interdigit  command under call-manager-fallback.
