I upgraded my system from 1.3.2 to 2.0.3 and cut paste the same configuration for trunks, inbound routes, outbound routes, extensions, etc. However I had DISA setup with IPKall incoming trunks and now the DTMF tones are not recognized at all. Not sure though if this is specific to IPKall. I don't use incoming DTMF for any other trunk or use. The IPKall trunk configuration is (User details): disallow=all allow=ulaw,g729,gsm dtmfmode=rfc2833 I have tried dtmfmode=info and inband with no effect. Please help. Thank you.
