AT&T T1 Outbound Issues

Hello,

I am trying to get some help with configuration of a T1 on a IP office 500 V2.

The signaling is ESF, B8ZS, CPE.
Clock Quality is set to Network, CRC Checking enabled.

I have tried Direction Bothway and outgoing.
I have tried Bearer Voice, Data and both.
I have tried E & M - Tie, Ground Start, Loop Start, E & M - Switched 56K.
AT&T told me the line is a Wink start.

When I make an outbound call as this is only for long distance I get a fast busy. The AT&T tech wasn't sure what the issue was. I am hoping some of you might know. I was thinking it was a similar issue to the NI2_CALLED_PARTY_TYPE=UNKNOWN but I am unsure how to specific this for a T1 circuit.

Thanks for any assistance.

Under IPO manager I put them in service. Is this what you are referring to?

yes, and your positive you have it configured correctly? Also line sub type should be Pri and switch type should be NI2, At lease that is how ours is set up

I am not. I only received information on the framing, zero suppression and wink start. The system comes up and goes idle. You can see the configuration information I have and a test call.

On the channels tab make sure they are put in service

Harkening back to Merlin Legend days and T1 services, it would normally be
Clock > Network
Line Sub Type > T1
Framing > ESF
Zero Suppression > B8ZS
Line Signalling > CPE
Direction > Bothway
Bearer > Any
Type > E & M - Tie
Incoming Trunk Type > Wink-Start
Outgoing Trunk Type > Wink-Start

Are you sure they are programmed as a real T1 versus a PRI? I haven't had ATT deliver a true T1 for years. It is always a PRI, NI2. Try changing to that versus T1.

Do you have access to System Status? Does the T1 show it comes into service or does the trunk stay out of service?

It shows idle in system status. I can see the call on channel 24 when trying to dial out.

Are you sending the main number out via ARS? Maybe ATT doesn't like what they are seeing.

I am, should I try to just dial with a line id?

Is the main number associated with this LD T1 or with their other PRI/etc? It could be that if you are sending the main number and it isn't associated with ATT's LD T1 it is rejecting it.

Your ticket from ATT didn't post properly. Have they said what they are seeing on their end? Do they see the call attempt? If so, they should be able to see why they are rejecting it.

I am waiting to hear more from them as I sent them information on the configuration but I don't expect a speedy response.
