Short code ...

[Vijay Patil]

We are having a setup where  2 Vender providing PRI services ...with the DID range

A. 6272 0100 - 0849

B. 3498 8000 - 8999

Every user is configured with the PRI A DID eg  6272 0555 if PRI A goes down user IP Phone must able to do incoming & outgoing calls.

Also need to create a short code for internal calling Me having doubt here is it possible to create a Translation Pattern like *[08]XXX....to reach the user 6272 0555

Hi,

1. You can apply the calling party manipulation at route group level. Have two route groups under route list. Configure route group1 for PRI A and route group 2 for PRI B.

Incoming calls are not in your control. It is your Telco who decides the same.

2. Translation patterns are so much granular in nature and serve most of the practical requirements. With the example you gave, you can apply transformation mask as 6272 0555. So when ever dialed number will match the translation pattern, it will route the call to 6272 0555.

1. Unless you are using MGCP, you can also use digit manipulation in gateway, configure translation profiles for calling number and associate with voice-port of PRI B for outgoing calls.

Hello Vivek ,thanks for replay...understood some point...

if the primary PRI down how can is use the secondary PRI for outgoing calls...where my number to particular user are same as 6272 0555 this will configured on IP Phone as extension

Vijay,

This can be very simple or it can be very messy and complex.

The easiest solution is to put the PRI in the same Route group and have PRI-A as the primary and then use top down algorithm for your distribution.

With this when PRI-A goes down, your users will still be able to use PRI-B but the calling number will be the main number of PRI-B. Users will not be able to present individual CLI numbers on this PRI.

The second solution is not sustainable. This is for you to use digit manipulation such as calling party transformation. With this you will have to manipulate each individual numbers on PRI-A to present the CLI of PRI-B. This for me is not advisable.

Hello Ayodeji...

Got the ans for the incoming we need to do the translation rule on voice Gateway..

but i am not clear how the out going work...as you mention abov got the point that need to give priority in the RG...

we already assign PRI-A DID as a extension to the IP Phones & UDP...but how the outgoing call works through PRI-B...where the DID range is different   (eg

PRI A. 6272 0100 - 0849

PRI B. 3498 8000 - 8999

)

Hi Vijay,

Deji has provided nice tip however note that using both PRI's in same route group will work only if you are using MGCP, else (for SIP/H323) CUCM can not control the fallback from PRI A to PRI B. You will have to configure gateway appropriately (using preference command under dial-peers).

If your DN is assigned the same number as DDI, best is to use translation profiles in gateway and assign to voice-port of PRI B.
