atcomsystems.ca/forum Forums TDM Business Telephone Systems Inter-Tel Telephones & Systems Outside Voicemail message length to short

I just setup an Axxess system Version 11.01 with a Linux EVMC. They are using Pots lines that are proviced by AT&T over a VoIP ATA. We are getting complaints that callers leaving voicemail messages only get 2 - 3 seconds of a message before they are dropped. A conversaion to a phone works fine. Internal messaging to the voicemail boxes is normal, messages can be left to the full allowable timer. AFAIK the caller hears nothing other than a click. The minimum message length is set to 1 sec.

Any ideas what is going on? Talkoff?? I remember the problem but not the remedy. Getting to old to be working on these old systems :))

I would start by running a hybrid balance test on the CO lines. From there, try the twist settings under Voice Processor / Timers & Limits.

Increasing the twist settings makes digit detection more sensitive, decreasing them makes digit detection less sensitive.

Increased sensitivity might cause talk-off, where voice is mistaken for DTMF. Increasing digit timers should correct that.

Thanks DND-ON

I will try that.

Just checked the system and the settings for those were set to unlimited. Looked at the Help and set them to default :

high to low twist (Play) 8.2
high to low twist (idle) 5.2

Low to high (play) 9.2
low to high (idle) 8.2

Will go from there

Thanks again

I would check with AT&T. There are settings they can change to duplicate a Pots line.
Sounds like it see disconnect to quickly.
