Call Masking

[jamesalston]

Hi

I have a setup in which callers dial a help desk number 2XXX and get the option to press 1 or 8. 1 transfers the caller to an ext 3xxxx and 8 to ext 4xxxx and that works fine.  However when the choice has been made and Unity Connection(8.5) transfers the caller, the ext 3xxx or 8xxx is displayed and we do not want the actual extension shown. Is there any way in CUCM(8.x) or UC(8.5) to mask the extension as its being transferred?

The techs already have their ext's masked when they dial out to folks within the company but I can't figure out how to extend that masking once Unity Connection transfers the call. Thank you in advance for any help.

You can try with a TP that can only be reached by CUC for those calls and mask the number there.

So 2XXX -> CUC -> TP -> 3XXX/8XXX

No luck using a TP so far, perhaps I'm not doing something correct. Thank you for your help anyway

Jaime is correct that you should use a translation pattern to do this, however you also need to make sure that the partition with the extension being dialed is not directly accessible  by the Unity Connection server, it should have to go to the partition that the translation pattern is in.

For instance, if 3XXX is in the Internal-Restricted partition, then Unity may have access to the Internal partition that has the translation pattern (which then in turn has access to the Internal-Restricted partition with it's calling search space).  If you don't segregate it like that, then the phone will always be chosen when calling because the directory number is more specific.

Hope that makes sense.

Thank you Jaime and John with your help I've got this working like I want it to. Before I posted my issue here, I opened a TAC case and the engineer told me that it was not possible to do. Hmm at any rate, I appreciate your help.
