adding "0" in front of the caller number

[chkt1]

Please show the method for the following case:

Insert a "0" in front of the caller number, as a result the missed call will include "0". In this way, users can just press dial on the missed calls for returning calls.

CCM version : 4.0(1)sr2a

OS version : 2000.2.6sr5

voice gateway use MGCP

Hareware platform is MCS7825H-3.0

hello.

on the router you need :

translation-rule 1

Rule 0 ^1 01

Rule 1 ^1 01

Rule 2 ^2 02

Rule 3 ^3 03

Rule 4 ^4 04

Rule 5 ^5 05

Rule 6 ^6 06

Rule 7 ^7 07

Rule 8 ^8 08

Rule 9 ^9 09

and then on the voip-peer to the ccm:

dial-peer voice 2 voip

preference 1

destination-pattern [your numbers]

translate calling 1

session target ipv4:....

....

My colleague cannot explain the fact. The voice gateways are running MGCP ptotocol.

The exchange only forward 4 digits to the CM system.But the DN of the ip phone have 5 digits. e.g. 34900. So we had modified the configure of the MGCP voice gateway to append a digit "3" in front of each incomming call.

The exchange provide caller information, the missed calls in each 7970/40 phone will display the DN of caller. e.g. 23456789

User need dial "0" to dialout to PSTN.

We wants to modify the missed call to 023456789. So user need press one button to callback the incomming caller.

Question: How can we fullfill this task in voice gateway running in MGCP protocol.

Thanks in advance for your help in this case!!

Thanks for your reply. But, your suggestion is only suitable for H.323 and not for MGCP. Please give additional suggestion for MGCP protocol.

Hi

Go into service parameters for the callmanager service, click advanced, and in the "Clusterwide Parameters (Device - PRI and MGCP Gateway)" section there is a "National Number Prefix" - if you put 0 in here this should do what you want.. If it doesn't work you could try putting the 0 into the other similar parameters (i.e. the 'Unknown Number Prefix') as your telco may not mark the number as 'national'.

If this doesn't work you can do the following:

Create a partition called MissedCalls_PT, then a CSS called MissedCalls_CSS. Add the partition to the CSS.

Then create a translation pattern in the MissedCalls_PT, that prefixes 0 onto the calling number. Set the CSS of the trans pattern to whatever CSS you would normally put on the gateway.

Then set the MissedCalls_CSS on the gateway.
