I've got a Nortel ARN that has worked fine for 10 years, most recently on BayRS
13.2. We subscribed to Vonage and installed four VOIP adapters on our network and now have problems.
Basically, voice calls are fine so long as no traffic goes over the link. If you initiate the call, then, for example, begin an FTP download over the T1 link, the phone call immediately goes garbled and is hardly usable.
I upgraded the router to 14.0 and enabled both DiffServ and RSVP, but do not know how to use them properly.
Our support contract has run out and I'm investigating getting a renewal so I can download the latest BayRS but I'm wondering if this will solve the problem or if there is something else I can do.
Any advice would be greatly appreciated.
