Hey all, trying to help a client whose Nortel BP went out of business years ago. Client has a 2050 on his laptop he uses in the office without issue but gets no audio when running over VPN. Looks like all signaling is working fine; DN registers and can make and take calls (can hear the numbers being pressed as dialing outbound) but no audio in either direction. I have an Avaya/Cisco voice background so I am comfortable with troubleshooting this kind of thing but am starting to think there may be a system setting that can help out here..?
Client uses Sonicwall NetExtender (SSL-VPN client) on his laptop (win7) and appears to have full connectivity through the Sonicwall. Client directs the 2050 to the internal IP of the BCM450. At first I was wondering if there is a setting in the BCM to force all audio to pull DSP resources from the BCM instead of audio streaming directly between the clients. In the IP Office world, there is a simple "allow direct media path" checkbox on the VoIP extension that needs to be disabled. But I continued testing and even if I call to the outside world I do not have audio either, which makes me think this is not the issue. Thought it may have been a Windows firewall issue so disabled that all together for a quick test and no change in performance.
System software version is: 8.0.1.05.329. Not entirely sure what softphone firmware he is using but it is Nortel branded; I am using 3.04.0003 of the 2050 for testing from my office to see if I had different results to rule out the client/remote side network firewall and his laptop as culprits. Wondering if there is a known bug or issue with system software or a provisioning fix that may be able to resolve this problem.
Am I down to wireshark at this point for additional troubleshooting? If needed I can remote to my test machine and head out on site with another laptop to wireshark the system if need be but that is more intrusive than I was hoping to get. Threw a wireshark on my test machine NIC knowing things would be encrypted but I get a steady bi-directional stream of encrypted packets while on the call (what I have to assume is the RTP stream).
To add one thing to the mix, client says he had installed 4050 on test license and had audio working while remote.
Any thoughts/opinions would be appreciated, thanks!
