Blocking outbound caller ID

[Hershel]

I have a client who would like to selectively block their outbound caller ID.  They have a PRI

Any ideas?

[markdevoll]

what about using *67? something tells me that it wont work on a pri but you might try it

Hershel,

This has been an issue for a long time and part of the problem is that we do not have an easy way to do this. First of all you need to find out if the carrier will accept a code or are they looking for a flag to be set for private calls. If there is a code then they would need to use that code when they call out, but if they are looking for a flag to be set on the setup message then we don't have a way to do that; even though I have asked for it a million times already. You can have it setup on Police Departments, in the US, that if they see a certain outbound Caller ID then they are to block it when sending Caller ID out, but I have never been successful getting carriers to do this for other customers. The only other option that I have been successful with is installing a POTS line on the system that they would direct access that by dialing a "feature code" which has a numbering plan reference to go out that POTS line, remove the "feature code", and insert *67, unless *67 is the "feature code" that you use to do this with; I made that read easier than it is though.

Thanks,

TE

I called Mitel tech support on this and the only thing they recommended was to create a hot desk user with caller ID 000-000-0000 (if your telco will allow you to send it).
Someone who wants to 'block' their caller ID can then log into this hot desk user, make the call, then log out... yes, very clunky to use

Down the same path as lowradiation's post, but easier:
Use one of the built-in SL ports on the 5000.  Set it to send a bogus CLID (CALLING PARTY NUMBER field on phone programming). Also program SL as house phone to dial 8 (outgoing).  Loop that SL port to a LS port on the 5000.  Put a line key for that LS on user's phone (or dial the trunk ext).
Now user presses the line key or trunk ext. Call leaves on the LS, re-enters on the SL, which dials 8 and delivers ARS dial tone.  User dials number.  CLID displayed at distant end will be that of the SL port.
If you do this a lot you could have multiple loops (as trunk group) to allow more than one call.  I've also used this trick where I just needed to deliver DIFFERENT caller ID for a second company when both companies used the saME STAFF.
