no ringback tone from h323 gateway

[sarali]

I am using 3640 as a h323 gateway, using ios 12.2.(10a).

i encountered a strange problem, when i call from ip phone to mobile phone from one mobile operators, i can't hear a ring back tone. my country has 3 mobile operators, when calls are made to the other 2 mobiles operators number, and all fixed lines it is working fine, can hear ring tone.

Below is my config:

dial-peer voice 100 voip

destination-pattern 6370....

session target ipv4:10.228.204.5

codec g711alaw

!

dial-peer voice 200 pots

destination-pattern 9T

direct-inward-dial

port 2/0:15

!

what am i missing?

The following doc has some good tips on troubleshooting no ringback:

Hope this helps

Did you try putting "progress_ind connect enable 8" under the dial-peer voice pots?

Hi,

The link of rosalasa is fine.

just write on the dial-peer pots the command "progress_ind alert enable 8"

If you cannot find it with the help command it's normal.

I also noticed that without this command, I had lots of delay for the ring tones for calls from IP Phones through GSM phones. For example, when I put the IPphone on hook before the called phone answered, this one continued ringing during about 2 seconds.

Bye
