Hi,
I meet some kind of a problem in my IP Telephony design.
All my DNs in CUCM are 9 digits long.
The PSTN Gateway is a CUBE which have 2 SIP Trunk : One to the CUCM and one to my provider.
On incoming calls, the provider shows 10 digits number for the caller and the called.
I route DN to the CUCM, strip the first digit with a translation pattern, match my ip phones dn... Everything is fine.
But the cube is also a srst gateway in case of a crash of CUCM.
If CUCM crashes, IP Phones registers to CUBE/SRST with their 9 digits long DN.
On incoming calls, as I said, provider show 10 digits number for the called.
As their is no SRST dial peer matching 10 digits number (all DNs are 9 digits), incomins calls are not working.
I tried to use a voice translation to strip first digit of the called number in SRST config or in the incoming dial-peer, but it does not seems to work.
When I use translation in SRST config, I guess that the dial-peer selection is made before translation.
When I use translation in the incoming dial peer config, it does not work. I think that I can only use translation on outgoing dial peer, is it correct ?
Does someone know a way to strip first digit before outgoing dial-peer selection ? So I wont have any problem with SRST and, as a bonus, I won't have to strip first digit on CUCM side.
Thanx for your help,
Bastien.

Hi,
You can do translation on incoming dial peers.

Be sure to match whole DNIS number & not only incoming called-number

You're right it works .... I did not implement the transaltion on the good incoming dial peer.
thanx a lot for your help,
Regards,
Bastien
