Hello,
I was hoping that you could help assist me with a issue that I am facing with my current local PBX box. Due to some phone issues we had to reload the NIC driver with the latest one from Intel. We are currently running a Intel I219-LM.
Upon the reload of NIC driver we lost our 224.0.1.75 Multicast Group for IPV4. Following the guide provided by 3CX (https://www.3cx.com/docs/plug-and-play-ip-phone/) I ran the following command and see the information below:
Interface 1: Loopback Pseudo-Interface 1
Scope References Last Address
---------- ---------- ---- ---------------------------------
0 0 Yes 224.0.0.251
0 1 Yes 224.0.1.75
0 2 Yes 239.255.255.250
Interface 3: Ethernet
Scope References Last Address
---------- ---------- ---- ---------------------------------
0 0 Yes 224.0.0.1
0 2 Yes 224.0.0.251
0 1 Yes 224.0.0.252
0 3 Yes 239.255.255.250
I can't seem to figure out how to properly add the 224.0.1.75 to my Ethernet Interface. Upon further diagnostics found that Windows 10 has removed the Adapters and Bindings tab (Thanks Microsoft!).
Saw some mention turning off the automatic metrics but unfortunately the phone still doesn't find my local PBX system to connect and provision the phone.
Wireshark shows the phone trying to reach the local PBX but never hears from PBX.
Any help would be greatly appreciated in getting this issue resolved.
TLDR Version: Reinstalled the NIC Driver to current from Intel due to issues only to find that now can't provision any phones due local PBX not seeing multicast request. Tried looking at results in wireshark and following 3CX guide. Changed Automatic Metrics and still running into issues.
