[Asterisk-Users] Sending DTMF to PSTN problem with SIP

[CClarke]

Dear All ~

I have * setup & running ok (with two Wildcard X100P's to PSTN). I also have
two analog phones connected into same through a SIPURA 2000. These work fine,
except that when I call out through PSTN & try to send DTMF tones to (say) a
remote PBX to dial an extension, the gain seems to go wild (high), and the
DTMF tones are not recognized at the other end.

I tried setting the SIP2000 to use inband dtmfmode (as opposed to auto), and
likewise in sip.conf, but no success.

btw, I've also set relaxdtmf=yes in zapata.conf since inbound calls sometimes
seem to have trouble dialling extensions.

A soft IAX phone (e.g. DIAXPhone) works ok, so I suspect my SIP2000/sip.conf
setup, but can't see what I'm doing wrong.
