IP office with PRI to telepacific adtran via T1 via channel bank which TPAC converts to sip trunks

[RodneyMcSnow]

I have an IP office 500 V2. There is a single PRI T1 card in slot 2 port 9 which connects to the Telepacific Pri T1 on the Telepacific Adtran channel bank.

Now, Telepacific Converts the pri t1 to sip trunks on their channel bank and this is where the fun begins.
When I call any local or long distance number the other party reports that they do not receive the caller id info 50% of the time.
I have verified with Telepacific This morning during our telco meet for 6-hours that we have a fractional T1 PRI,the D channel is on port 24 with B channels 1 through 12 using ni2 protocol, ESF/B8ZS. All of which is correct and verified in the Avaya. Licenses for b-channels is 16 and canid Essential Edition license. Please note , calls route out of the Avaya IP Office no problem.
Callers on the other end do not receive caller id for whatever reason and incoming calls do not have audio most of the time so the customer cannot hear the person calling. Therefore the person either emails the customer or calls from a different phone till they get through.

When I connect in analog Pots line to the combo card and set up a dial plan (short code 8 dial speech line group 7) I can dial 8 to access the pots line from any phone the caller id is presented to the other phone, local or long distance with no problems.

This is a simple traditional PRI T1 to the IP office but for some reason something is going on with the Telepacific sip trunks and Telepacific Repair states there's no problem as the circuit tests clean and they are unable to duplicate the call.

Has anyone worked with a traditional PRI that converts to sip on the back end of the telco company? I'm open for suggestions!
Personally I'd rather see a traditional PRI T1 installed from the telco company instead of the sip junk.

By the way we already replaced the Avaya IP office chassis and all of the cards and no change with the sip issues.

We do PRI's with TelePacific using their IAD's all the time, and for the most part, never have troubles with them. Does your ARS route for the PRI include sending our your telephone number? Run Monitor, turn on all the checkboxes on the IDSN tab, and you will very clearly see the number that you are calling along with the number that you are sending out as your own caller ID. If those are correct, have them log into the adtran while you run monitor and place test calls until one fails. Then they can see where it is failing on their end.

 

[RodneyMcSnow]

Yes we did that this morning and the number I'm dialing is the number that shows up in the monitor and also is the number that's being sent to the ADTRAN which then goes to the tpac switch and then to the broadvox soft sip box from Telepacific.
TPAC never sees an issue but we have successfully duplicated it several times.
No audio is typically an rtp issue and again TPAC says all is fine.

 

[TouchToneTommy]

Yeah, but since they are handing it off to you as a PRI, you know the issue is their transport from the Adtran to the CO, and not yours at all. Hammer on them, they've usually been pretty good about finding problems. Sometimes they will wipe the Adtran and rebuild it, or replace it altogether.
