Unable to make outbound calls

I keep getting:

== Using SIP RTP CoS mark 5
[Feb 27 16:22:53] NOTICE[2098]: chan_sip.c:20792 handle_request_invite: Call from ‘1310’ to extension ‘5’ rejected because extension not found in context ‘DLPN_ROIOrlando’.

as soon as 1 number is pressed, goes to beeping tone…

extension has been deleted and recreated, same for its ring group membership

please let me know what files you need to review


As ring groups are a GUI context, you probably want the FreePBX forum on their web site.

To continue debugging this as a *.conf problem, you will need to provide all the relevant dialplan and sip.conf information.
