[Asterisk-Users] mISDN + chan_misdn and DTMF

[Alex]

Asterisk CVS-HEAD 30/3/05 + mISDN + chan_misdn = everything works fine but
outgoing DTMFs are not sent to the called party when placing calls from SIP
clients to PSTN (ISDN). On the contrary, incoming calls from PSTN can send
DTMF to Asterisk.
I've already tried every combinations of dtmfmode (inband, rfc2833, info)
either in sip.conf, either in clients options, with all codecs. I've also
tried setting SIPDtmfMode() before dialing, but had no success.

Any hint would be greatly appreciated!

TIA,

Alex
