stripping the digit didn't fix it. It turned out to be a true protical issue. Seems to be a AIN / PLNC signaling issue. Not exactly sure what that controlls, getting info from our DMS switchman. It seems AIN is looking for a precursor code to preform features assosiated with NI-2. If more than 10 digits are recived and it doesn't get the correct signal it will reject the call.

interesting. Still strange that 10 digits were processing correctly and yet stripping the 1 did not allow calls to be processed. Guess it could have been programming issue in the CO that it would only process the local area codes without the other signaling.

Dane the issue seemed to be with a feature on NI-2 called AIN PLMC. As per our switchman, this feature is used for NI-2 features. It rides on the D chanel. 10 digits aren't affected but when doing 1+ or anything over 11 digits, ie 011 ect. the DMS-100 is looking for a preemble to activate enhanced features. Not sure exactly what this means, lol. I'm just a carrier tech who worked on PBXs for 26 years so I got draffted to help translate between our Switchman and the Mitel vendor. We are located a little north of Allentown PA

Well that being said, it seems weird that the PBX would route 10 digit local but not 10 digit LD. Still you have it working and that is the most important thing, but I am still curious. Anyway thanks for the response.

I heard a tech support guy once say that some of the switches are "a bit slutty" -- they'll work with a wrong protocol, but not well. That's probably what happened here.

I've also heard of problems with NEC switches trying to get NI-2 protocol from a DMS CO (Usually request a different CO when that happens).
