I'm trying to configure my SoundPoint IP550 with my provider. I got it working but the calls drop after about 20 seconds or so. My provider suggested turning off 100REL. which I think is also know as PRACK. Does anyone know how to turn this off?
welcome to the Polycom Community.
I would suggest you take a wireshark trace via a spanned port and check for the root cause of the dropped call.
I just checked and we have a voIpProt.SIP. supportFor100rel Parameter but I believe it is only in certain Software Versions and may need to be requested as a hotfix via your Polycom reseller and/or Polycom support.
