Core module upgrade breaks trunks

Hi. After I update FreePBX from Core version 13.0.113 to version my trunks no longer register. I receive the following msg in the log files.

res_pjsip.c: Unable to apply outbound proxy on request OPTIONS to endpoint MyTrunkName as outbound proxy URI ‘’ is not valid

res_pjsip/pjsip_options.c: Unable to create request to qualify contact sip:[email protected]:5060

So if enter my outbound proxy as the trunk registers. However when making outbound calls I get the msg “if you would like to make a call please hang up and try your call again”

Logs - specifically /var/log/asterisk/full for the offending PID on the call that failed (the PID is part inside the square brackets on the log lines).
