Description:I have been trying to use H.323 to trunk Asterisk 1.6.0.9 to Altigen PBX. Everything works fine now, except the DTMF transfer issue. The DTMF mode Altigen uses is h245alphanumerica, I made the changes in the ooh323.conf accordinly. But it just can not work. From the wireshark, I can not the 'H.245 user input' tranferred to Asterisk from Alitigen.

I am using asterisk16-addons-ooh323-1.6.0.2-3, and following in my ooh323.conf file. Any insights would be appreciated.

Could you provide wireshark/tcpdump cap file for more detail analysis?
it's possible that altigen indicate own dtmf signalling incorrectly.
