when i call the router i get the below
[2018-02-20 10:47:41] WARNING[12837][C-00000059]: chan_sip.c:24084 handle_response_invite: Received response: “Forbidden” from ‘“tom.flod” sip:[email protected];tag=as21b306d3’
i have the same router in another branch and it works great.
second part of the question is there a link i can read to see warning code meaning
Forbidden is pretty specific. For some reason (there are a few) the remote machine said “No”.
The logs in the router should give you the particulars, but there’s a problem with a password not matching (if you have one), an ACL not allowing the connection, or the username you didn’t specify didn’t match the one required by the IOS config.
Note that the ‘/var/log/asterisk/full’ log might (or might not) give you a little more detail in the lines above your “Received response” line.
