Further to this message, DTMF works with PMCU but not with PMCA which is the native format for this sip provider.

I have tried the following in the gw profile <param name="dtmf-type" value="rfc2833"/> <param name="rfc2833-pt" value="101"/> <param name="pass-rfc2833" value="false"/ I should add that this sip provider works fine with asterisk. Anyone any ideas? Regards
