Dial-peer Config.

[jcd30]

I am introducing a new location in to our dial plan. I am going to set the site up in Call Manager and have the site connected thru a 2811 Router running H323. The problem I need help with is the site's DID numbers are 46XX I already have 46XX numbers at our Main office so I am going to have to make there extensions in Call Manager something like 36XX and make a dial-peer in there Gateway change this to ring there phones at 46XX. There is where I am running into the problem, what would I do in the dial-peer on there router to say drop the 3 and add a 4 on incoming 4 digit calls.

Also how would they call 46XX extension at our main office without ringing phones at there location?

Please help.

Thanks
CD

You wouldn't do that on the dial peer, you need to do that on the call manager using translation patterns.

You will have to separate the two 4xxx DID coming in with separate css so they do not see each other, therefore no conflict.
Then translate the new 4xxx range coming into the call manager to 3xxx using translation patterns.

Thanks for in post, could you give me a little me information on how that would look or point me to a link that I can see an example?

How would that work on the branch end when they dial 46XX they are still going to get there own branch instead of an Extension at our main office. They have a Nortel system that I am going to tie into the Gateway via a T1 with 6 Lines. I could tell them when they need to call a 46XX extension at our Main Office to first dial an 8 that would put them in the line poll for 4 digit dialing. Let me know if you have something different.


Thanks

It sounds like you have a solution for the conflict and willing to introduce 8 as the site code for the Main Office. You may want to see how this will scale, as single digit site code is too restrictive.

The possible solution is to:
Have the remote site dial 846XX to get to main site. Create a voip dial peer in the 2811 to match 846XX and send it to Callmanager. When it gets to Callmanager, create a translation pattern with 846XX, mask it to 46XX, and have the CSS see the Main Office extension's Partition.The call will get to the proper extension.

If the main office wants to call the remote 46XX DN, have them dial 746XXX. Make 746XX as route pattern, sent it to the 2811 via h323. At the H323 GW, create a pots dial peer with a pattern of 746XX and send it to the proper voice ports. Forward only 4 digits in the pots dial peer.

Scaling of the possible use of site codes would be a concern. A 1 digit code is too restrictive.

The above may be something you want to do. There are different ways to do what you want.
