Asterisk knows of three different ways for DTMF signalling, in-band being only one of those. There are also rfc2833 and info (SIP INFO) signalling. You could try and set the dtmfmode= parameter in sip.conf to one of those. voip-info.org has some info about it. On the other hand it might be the case that your SIP PBX does _not_ generate SIP INFO or RFC messages but the DTMF signal is poor, not allowing reasonable operation. I had that one with a SIP provider once, effectively meaning I could not remote-control the voicebox.
