Forwarded calss wont disconect

[techguy137]

Hello
I have a customer that has a Partner ACS R7. 2-308 cards, Partner Messaging.
They have upgraded to what is known in this area as an IA circuit (integrated access). This is a T1 that shares data access with the phone lines. The lines are converted to FXS & connected to the Partner system. They use lines 1-4 on the processor.
On this system they use an automated attendant that transfers the caller to certain extensions that are forwarded via button F11/99 that is to a cell phone. These people are dispatchers & the forwarding changes on a daily basis.
My problem is that the lines don't always disconnect. If a call comes in & forwards out to a cell phone it will just hang until someone clears the lines from the forwarded phone. I have set the line selections on these phones to try & isolate the problem to a specific line. It doesn't seem to matter which line is selected. I have had the local telco look into the router & adjust forward disconnect timing & such. I also have installed 2 Viking CPC-1 (calling party control units) on their main number & the out-calling line. This has had no effect.
The local telco has blamed it on the PBX, but this problem didn't start happening until they converted over to this IA circuit.
Anyone out there got any ideas????

There's nothing you can do on your end. The provider is not giving you "Reliable Disconnect", "CPC", "Cutoff on Disconnect", "Open Loop Disconnect", Loop Start Disconnect", or whatever their terminology for it is. Many alternative dial tone providers don't even know that it is a standard feature on a "real" CO line. Many will argue with you, and the cable company will provide the Viking CPC boxes, but won't install them, forcing you to bill your customer to put them in, and they still won't solve the problem.

Perhaps they would be willing to change the IAD? Most providers I've seen use Adtran Total Access, and they usually work pretty well, but other brands, and cable company ETMAs, not so much.

Thanks Tommy.

Yes I agree with you 100% They have argued with me on this.They say it isn't their problem The provider is Centurylink, Formerly Qwest. The router is an Adtran Total Access. I was hoping somebody had a work around for this.
I have had a couple of instances where I have had Qwest replace their routers due to other issues, but not like this.

I think I will start with them and make them replace this router.

Thanks again Tommy for your help.

on that topic
I had a service ticket in with a line provider and the "tech" calling me back said that the disconnect signal on "regular" lines is a # DTMF signal being send and their device would not be able to do it. Had to clarify that with the guy and after calling them about 4 times I finally got a tech that knew what I meant and he actually went into the programming and turned it on. No more problems with that customer since then
