Denial event 1218 2

[charlottemccloud]

Hi all-

I just switched carriers for my PRI and I'm having a strange problem:

I've got toll free numbers coming in and the DNIS matches a VDN that goes to a vector with some choices. Some of the choices route calls out to a offsite telephone number. Worked fine until we changed carriers. Nothing in the trunk group or vector changed. But now when I choose an option to route back out, the call will not go through. I traced the TAC and got denial event 1218 which talks about invalid IE contents. Never heard of this one. Is there something in the trunk group I should change? Thanks, in advance, for your response.

Some carriers use Network Specific Facility indicators to identify the inbound type of call. Under certain circumstances, the network will refuse a tandem call from a PBX, such as an inbound toll-free being sent out of the switch to another toll-free number. The way to solve this is to modify the NSF indicator. Do 'change isdn network-facilities' and create a new entry called 'strip3' with a type of '3'. Leave the coding field blank. Find out what Route Pattern you are using for the calls that are failing and put 'strip3' in the Service/Feature field.
