Hi,
Looking for some help/advice from the community.
First issue is the Activity Log is full of the following error
Exception: SipMessage::Exception Missing header Contact @ SipMessage.cxx:1393
Second issue is that calls drop at random. After some digging around last week the system was stable for 3 days but today calls are dropping all over the place. There is no set time that the calls drop, it just happens anywhere between 5 and 30 seconds. Both Internal and External calls are affected.
The 3CX server is cloud hosted, onsite there is an SBC running as a Hyper-V VM, there are 10 Yealink T42S phones connected to the SBC.
Firewall is a Ubiquiti Unifi USG4P with Sip COMMTRACK disabled
Switch is a Ubiquiti Unifi 48port POE switch
Phones all run on their own vlan, latest support firmware has been pushed to the phones
I am rapidly running out of ideas so any suggestions would be appreciated.
