Hi all ,
I have Elastix 2.5 which runs by Asterisk 11.7 and I have a problem with incoming calls.
If someone calling our number he can hear IVR but while press any button there is no action,
After checking debug logs I found the system can not recognize payload 111 as I use rfc2833.
Here is the error: Found unknown media description format telephone-event for ID 111
What I can do solve this issue?
Upgrade to a supported version of Asterisk.
With that old a version, you are probably using the obsolete chan_sip, so use “sip set debug on” and the full log, to capture the actual SDP received.
Also note that the error relates to “telephone-event”, not 111, although Asterisk 1.4, and even earlier recognized that. 111 is not pre-assigned and the objection is to assigning it to telephone-event because that name hasn’t been recognized, but I can think of no reason for that happening. I can’t even imagine that Elastix removed support.
