Hi, I am currently having a problem where I am making outbound calls via IAX, these calls are then being routed by my provider through a SIP connection to a service providing PSTN access. The problem I have is the the DTMF is being sent inband over the SIP connection, and I am only receiving the DTMF inband on my IAX connection which asterisk is sensibly ignoring as from what I understand with IAX2 the DTMF should be sent out-of-band. I assume the simplest way to fix it is for my provider to put a dtmfmode=inband on the sip.conf entry for their PSTN provider, then presumably their asterisk would see the DTMF and send them out-of-band over the IAX2 channel, however, they are understandably wary of doing this in case it affects any of their other services which currently work perfectly... Is there any way to get Asterisk to listen for inband DTMF from an outbound IAX2 channel so that I can get round this problem in a simple way? (The reason I need to get DTMF on an outbound call is I am trying to set up a 'press 1 to accept the call' system for forwarding calls to mobiles). Thanks in advance, Alex Brett alex.brett@loho.co.uk
