Auto-Dial Emergency Phones on VG248

Unanswered Question
Nov 4th, 2008

Since upgrading to UCM 6.1(2) a client's Auto-Dial emergency phones hanging off VG248s have been failing to dial. I believe this is simply a timer, but I'm not sure what to tweak to fix the issue. The symptom is that callers pick up the phone and they hear a dial tone. These analog phones are programmed to automatically dial the emergency number (the auto-dialing doesn't come from CM). Anyone with info please share.



I have this problem too.

Hi Brian,

Is it possible that the Analog phones have lost their auto dial programming? Sometimes the line current keeps the programming onboard. Can you move one to a different line (off-site) to see what is heard? I always prefer the ringdown to be setup in CCM so you don't have to visit the phones if there is an issue like this.

Can you try setting one up in CCM.There is a great step by step here;

Hope this helps!

Hi Rob,

Thanks for the feedback. The phones work fine when connected to a VG224, so it's not the phones. I suspect some kind of DTMF timing or port issue. TAC is looking over log files after we ran some tests.
