Hello.
I have problems when trying to make call from 1 sip user to another sipuser, I’m using Asterisk Realtime SIP and Extension with mysql.
SIP phones from sip.conf working fine. I can even call to “mysql” phone - and it works for incoming calls too, but when I’m trying to make a call from “mysql” phone this error occurs:
Errors in Asterisk cli:
[Oct 18 14:43:50] WARNING[19430]: chan_sip.c:6023 sip_call: No audio format found to offer. Cancelling call to 1999
This is corresponding mysql entry:
