Caller ID via IP tie trunks

[johnharley]

I have 5 sites - all of them running CM 2.2. The hub is a SCC with PRI for inbound calls. The remaining 4 sites are CMC connected to the SCC via ip trunks. The problem is with the caller id. I get the caller-id info when I call to a station at the hub but when the call is transferred I get just the trunk group name. If one site calls the other I also get the caller-id. The IP trunks are setup for DCS.
How do I get the caller-id info for calls transferred from the hub to another site via IP trunks?

You can't. I had the same issue and if you do figue out how to make this work, I will give you 100 stars + I will be forever grateful.

I my example, I have 6 sights all with their own PRI and fully interconnected via IP trunks. The problem is that if a call comes into sight A, I see caller ID 9735551212. I press transfer XXXX transfer. The caller in sight B, first see's my extension then the name of the IP trunk group. The caller ID of the origional call does not flow through.

Now, I spoke with both my BP and Avaya. They both claim that this is the way is should work. I think that is crap and the caller id should flow though to the other sight. It works correct when you do a transfer from sight A to sight A, but not from sight A to B.

Did AVAYA tell you that the caller id is lost dur to the IP trunks or the transfer process?

I am going to pursue this and if I come up with a fix I will let you know

They didn't use the word lost. They just said that the PBX was working the "way it should". I think it is the transfer to another PBX that is causing it. When you transfer to the same PBX, it works.

I have a P2P T1 trunk and the same thing happens over it.

Let me know what you find out. This has been a hot issue for me...

The caller ID of the device making the transfer will always follow the call.

If you were to call from site A to site B, then transfer the call to site C and again to site D. The pbx's arent going to know that you want the caller ID of site A to follow the call to all those different pbx's.
