Call from CME to other PABX

Hi all,

My proplem is, when I call from my CME to an other PABX, the call was established successful and can hear the AA. But when I dial the extension, the call drop. Call flow as below:

1. Call to an other PABX number

2. Hear the AA voice

3. Dial extension number

4. Call drop

Below is my telephony-service configuration:

telephony-service
 sdspfarm units 10
 sdspfarm tag 1 confer2
 conference hardware
 max-ephones 58
 max-dn 300
 ip source-address 192.168.31.1 port 2000
 load 7942 SCCP42.9-3-1SR4-1S
 time-zone 41
 time-format 24
 max-conferences 22 gain -6
 call-forward pattern .T

Hi Nguyen,You've not

Hi Nguyen,

You've not specified the dtmf-relay to be used for these dial-peers. It looks like you are using h323 as the protocol to send the call to the PABX? Is that right?

If so, add the 'dtmf-relay  h245-alphanumeric' command to the dial-peers that are pointing to the PABX and try the call again.

Thanks
