I upgraded my PBX using the System Admin Module and this morning I find the phones not registering.
PBX Firmware:6.12.65-27
PBX Service Pack:1.0.0.0
Asterisk 11
FreePBX 12.0.54
I check firewall, I check PBX, and I find that there are no PJSIP Drivers available. So I head to Advanced Settings and I see that under SIP Channel Driver : Chan_Sip is selected, when I select both, Save and Apply Settings it still displays chan_sip and not both as selected, saved, and applied. If I go to create an extension PJSIP is NOT Available as an option for an extension.
