I’ve been experiencing an strange issue lately
I call via from voip provider to my asterisk machine with my did and start my IVR, it gets to a WaitExten(20) and a Background(menu)
But when I hit number 1 on my mobile phone for going to exten => 1,1,xxxx , this message appears on my asterisk console:
– Invalid extension ‘11’ in context ‘internal_extensions’ on SIP/voipprovider
Why this two 1 instead of just one ‘1’???
I’ve put in the general context of sip.conf relaxdtmf = yes, but nothing has gone better by the way 
Any ideas?
Howdy,
What are your dtmfmethods defined for the SIP peer?
Hello
Basically, dtmfmode=rfc2833 and as said relaxdtmf=yes
Since this doesnt have anything to do with dahdi or anything else, just 2 sip servers (external ip provider and my asterisk machine) I don’t know how to do this any better
Regards
Howdy,
What codec are you using?
Codec allaw
EDIT: By the way maybe this is something, if I press number 2, it dials correctly the extension exten => 2,1,xxx
Howdy,
That’s odd. If you’re using alaw, have you tried inband for the dtmf mode?
Hello,
Did tried with info and rfc2833 and nothing
But with inband works perfect!
Thanks
