We have a problem where incoming calls on the CDV line don't ring correctly on our
Nortel Venture phones (PDF link). Our other phones work fine receiving CDV calls though, and conversely the Venture phones continue to work fine with a separate Verizon landline that we also have. It's frustrating.
I need to find out if this Venture phone incompatibility is dependent on the brand/model of the EMTA modem used, or fundamental to the CDV service itself regardless of the EMTA unit?
I read a
previous BBR thread from last year with a similar problem. But Comcast's
incompatible equipment list doesn't mention these Venture phones (which were made by Nortel, then Aastra, and have since been discontinued). FYI I think these desk phones had cost us over $500 each years ago. More importantly, my family members
really want to keep using these phones.
Anyways we have CDV service at two houses: one service (a ported number) using a Scientific Atlanta DPX2203 series "WebSTAR" EMTA which snaps onto a large battery base, and the other service (a new number) using a newer SA DPC2203C2 EMTA which has front-mounted bays for battery packs.
In testing both have the same problem in that incoming calls come through as
intermittent and
abnormally short rings on the Venture phones, such that no Caller ID data is transmitted and the call cannot be answered unless I manage to pick up the Venture handset right in the middle of a short ring.
I went to a local Comcast service center in Houston hoping that swapping the EMTA may fix the problem, but they said that they didn't have any spare for me
One guy did tell me that they're expecting to receive Motorola EMTAs soon that he heard work a lot better. Should I wait for this??
