I’m having an issue with grandstream GXP2170 phones where randomly when there is an incoming call from a ring group, you pick up the call but your phone keeps ringing. You press “answer” and the call still keeps ringing. I’ve moved all of these users to a queue for testing to see if it is in fact an issue with the ring group, and it appears to be so. Has anyone had this issue before?
Notes: all phones and PBX are on the same PBX and network/vlan and not routed. FreePBX 12.7.4-1803-1. Asterisk 13.19.1
Any help/insight would be appreciated.
