I performed the traces you guys mentioned many months ago, it was detailed, but all it told me was that indeed the disconnect was thirty five seconds after the caller hung up, which by the way, I found was the true scenario, if the agent disconnects before the caller, no problem, if the caller disconnects first, problem.
Also I ran the test you guys suggested, calling from and agent phone to an agent phone, and there was no issue, I am sure it is in the Qsig variant, however, I can't convince the MSC people to change it. No worries though, we just received approval to purchase an Avaya 8710 with a boatload of goodies. Sorry about "straying to the darkside" however, I used to work for Nortel, and worked for Avaya as a tier three engineer for eight years, and I find the support and documentation much better, expecially considering my switch is obsolete, no longer produced or supported. I also don't care for the programming interface. In all honesty, I can't wait to see this thing hit the graveyard with the rest of our antiques.
BTW phones1 and JAAG, we receive our lines from AWCC, no PSTN involved, it goes over a microwave link in the call center to the MSC, they do all the switching control.
I do a lot of work around here for many offices, I went to the UNDP when I first got here, as marketing wanted me to sell them some E1s, I am not a sales person, but my company is short on talent, and does not understand the protocol of an organizational chart, so I spent my first few months bouncing around doing stuff that had nothing to do with PBXes, drafting proposals, sells, ad nauseum. Only recently have I gotten a chance to get my feet wet, we have so many issues, wiring nightmares being foremost, I also get called in to the US Embassy, and Ministry of Foreign Affairs, I have to wear a dozen hats, and am the only support person for PBX in my company, they are really wearing me out. JAAG, I will try to give you a call sometime when my head stops spinning.
