Since 188.8.131.52 (and still in 184.108.40.206) you can no longer forward or transfer a call to outside numbers when using SIP (VoIP) Trunks.
It gets rejected by the SIP Provider and the call fails.
Also using a FQDN in the “Outbound Proxy” field causes the registration to be rejected. Instead I am forced to input the IP manually. (Example is pbx.singlepipe.net doesn’t work, but the same as IP 220.127.116.11 does.)
Both of these worked in 18.104.22.168 and prior.
This is a MAJOR issue and needs resolved quickly.
It seems likely to be related to the conversion to PJSIP (from the older CHANSIP) in the newer versions.
I’m sure someone else has these issues, are there any workarounds or fixes.
