Need some help on an issue we are running into for one of our customers....
We used to be a Siemens dealer but moved to Vodavi (Now Veritcal) about 4 or 5 years ago and discontinued our dealership with Siemens.

We still have a HiPath 3550 at a customer site that has been running on a Level 3 PRI for years. The customer just switched over to another carrier (D&E) for the PRI and now all of their outbound calls are sending the 3-digit extension number as their outbound caller ID. The customer wants their main phone number to be sent but the new carrier is telling us that they can only send what our PBX is sending??? They use a softswitch as their CO for the PRI so I don't know if that makes a difference.
Anyway, my tech that is most familiar with the Seimens systems took a look but could not find anywhere in the programming to set what the outbound caller ID should be. Does anybody know if it can be done and where to make the changes?

Thanks,
Timbo
