Please, if any member of the group can support me, I have an asterisk which was working without any problem but I have decided to update it from the Asterisk certified/11.6-cert18 version to the Asterisk certified/13.21-cert6 version, finding the following situation:
At the moment of receiving calls from an SBC to the asterisk plant, these remain with the empty from, therefore, it looks for the default context which does not exist returning this way a 404 to the SBC. Now, if I do the test from a softphone call xlite, zoiper, 3cx is connected without news.
Error log relationship
chan_sip.c: Call from ‘’ (188.8.131.52:51383) to extension ‘1111’ rejected because extension not found in context ‘default’.
It should be noted that this same configuration worked correctly with asterisk version 11.
I appreciate the comments or observations.
