Externally call forwarding IP set

[mroberts]

I have a customer that has the following situation on a BCM50:

Calls from an internal phone, dialing out calling a DID back into the system, rings the IP phone fine.
Calls from the outside world to the same DID hits the IP set fine.

Calls from an internal phone, dialing out calling a DID back into the system to an externally call forwarded IP set, the call forwards fine.

If they externally call forward their IP phone to a cell phone or like a home phone, an intercept kicks in saying that the # is disconnected. This is with calls coming in from the outside world to the DID which is assigned to said IP set.

Someone calling thru the auto attendant, to the externally call forwarded IP set, the forwarding works fine.

This problem only happens when someone calls in directly on the DID assigned to the IP set and that IP set is externally call forwarded, the call will not go through.

HELP?!?!

did you set TAT and TRO and Network diversion correctly?

 

[mroberts]

Probably not since I don't know what those should be set at in order to accomplish external call forwarding?

Is it because the forwarding is being done from an IP set?

check that Network Diversion is set to "NO"
TAT= NO
TRO = YES

TAT and TRO are MCDN features - that shouldn't have any effect on this unless the calls are hitting IP trunks or a SL1/private PRI at some point in the picture, which it doesn't sound like from the description.

But, if the DIDs do come in on a SL1 PRI or IP trunks, TAT could be the solution.

I think the DID is coming over a PRI. Real quick, where are those settings in programming??

Thanks

i don't know exactly out of my mind
but its something like "ETSI -> Network divrs."
see manual for exact location

Have you tried moving the line to a digital set and eliminate the IP set .

Sounds like you are not sending all the digits to the phone company. Download and install BCM monitor that is going to show u the digits comming in and going out of your system. That software is on the main login page under Install Clients. I think that you need to increase yor public DN lenght.

The problem is with caller id presentation. when a call comes directly in from the CO on a DID, the phone system will send that caller id as the outbound caller id to the CO when the call is forwarded. this is not a number the CO expects to see from an outbound call, and thus drops the call. You can either ask the CO to allow all outbound calls regardless of caller id, or you can have the CO force caller id on all calls.
