XR500 NetDuma drops SIP packets
Hello,
I work for a VoIP provider and am home for the quarantine.
For some reason, I cannot get my Polycom phone to play nice with the XR500.
Looking at packet captures from the proxy where the phone is trying to REGISTER with, the register never arrives.
I already have SIP ALG disabled, NAT filtering to OPEN.
I have tried different SIP ports, and I have also tried to put the device in the DMZ. I can access the Web GUI of the phone when I have it in the DMZ, but SIP REGISTER still does not work.
I am on the latest firmware.
Any ideas here?
- This is actually something we're aware of and will be looking into. The only thing I could think of that would be blocking it is QoS so you could try disabling this entirely from the Anti-Bufferbloat option menu.
