Trying to find a resolution to conflict with my Analog Nortel Venture 3 line phone system(phones communicate on line 1 with each other) and the Erris TM 604G. Stutter ring(1/2 normal length), no Call ID, and difficulty in picking up line 1 all culprits. Found a similar post with Venture Phones and Comcast service from a few years back.
Owners manual for phones say a termination module may resolve interference from Non-Venture equipment connected to line 1 on the phone. Unable to locate such a module, and Aastra does not pick up their phones, assume this is a discontinued model, but widely available on the internet, some new, mostly used.
Any help would be appreciated!
