A customer got a fax in which more than 100 fax numbers (e.g. 012345678) of other companies have been pre-configured. Now they have changed to IP telephony and we have connected the fax through a Cisco ATA 186. With IP telephony they have to add an extra "0" while making an outbound call (e.g. 0012345678). The customer does not want to change all the pre-configured fax numbers and want us to slove this in the CUCM.
I know that there are two ways to slove this issue.
To create a separate Parition, CSS and Route Pattern (with extra "0"). I've configured this and it works fine.
But I have heard that you can also slove this with Translation Pattern. I've tried with Translation Pattern but it doesn't work.
I hope someone can help me.
