Hello to the group,
Again great project have worked with Freepbx for many years.
Recently installed FreePBX 15.0.16.44, all updates.
Very standard setup 3 sipp trunks and 14 extensions. Call flow works fine, main incoming Sip trunk to ring “all” ring group, can transfer and blind transfer from the answering extension no issues either to another local, or to an external number.
Standard extensions used, mostly Grandstream Gxp2170’s which are configured in pjsip format. Sipp trunks, configured as standard sip, not pjsip format. codecs are alaw and ulaw
When I call forward the extension (any extension) either to another extension, or to an external number from the set using the designated forward button or *72 feature code it does not work.
When calling the forwarded extension, it either completely ignores the call forwarding rules going to voice mail standard ring times, or gives me a recording telling me it is forwarded and repeats the number it is forwarded to then disconnects.
If I forward the local from Ucp seems to work fine.
This is the log file:

Have never ran into this before.
I am at a loss, spend some hours searching could not find anything which seems to be applicable.
Any help or insight would be appreciated.
