Off Hook Ring down

Answered Question
Dec 6th, 2007

I have an analog telephone (VG224 - MGCP) in an elevator. I'd like the phone to automatically dial an extension when it goes off hook. Is this possible?

I have this problem too.

Hi Frank,

You should be able to use the info in this doc to set this up (it talks about IP Phones but the CSS/Partition can be applied to Analog sets as well);

Hotdial on IP Phones with CallManager Configuration Example

Hope this helps!

Hi Rob,

Any ideas how to get this working on CM5.1, it does not allow you to have a null entry in the route pattern field. I've tried putting an ! in there however you still need to dial a digit to initiate the translation.

Appreciate your help.

Hi Ash,

I'm sorry we don't have CCM 5.x in the lab right now so I can't test this for you :( I am curious where you are being prompted for Route Pattern info?

These should be the only Steps;

Steps for configuring PLAR

In order to allow the phone to automatically dial a pre-configured phone number when the user goes off-hook, a CSS is configured with a partition that contains a translation pattern with a blank translation pattern string. This results in Cisco CallManager immediately matching this pattern. The translation pattern then transforms the called number (i.e. none) to the destination number (Hotdial) where we want the call sent.

Create a partition.(Maybe called Hotdial1)

Create a CSS.(Maybe called Hotdial1CSS)select the partition you created in Step 1 (Hotdial1) by using the arrows from the Available Partitions field, then click Insert.

Create a translation pattern.

From the Route Plan menu option click Translation Pattern and then click Add a New Translation Pattern. Select the desired partition name (Hotdial1) and CSS (Hotdial1CSS) that were previously created in Step 1 and Step 2. Finally, under Called Party Transformation Mask, enter the Hotdial number that you want the phone to dial when it goes off-hook. Click Insert.

On the IP Phone that you want to Hotdial when going Off-Hook apply the new Hotdial1CSS.

Hope this helps!

Hi Rob,

Thanks for your response, i was using route patterns instead of translation patterns. It's working now.
