Hi Team,
I believe there is a bug in VitalPBX. When the SIP Auth ID starts with a “+”, VitalPBX does not attempt to register.
I have a SIP trunk with an Auth ID that begins with +977… The SIP trunk works correctly with 3CX, MicroSIP Soft Client, and Grandstream Wave Lite. However, I am unable to get it working in VitalPBX 4.5.0-7.
I even hired a network troubleshooter from Fiverr, but they were unable to resolve the issue.
I am happy to provide the SIP trunk details if contacted by VitalPBX.
I look forward to hearing from you.
