Hello,

I have installed a summit with 5 C.O. Lines. All calls are answered by the AA. And transferred to what ever extension by requested by the caller. All is well but when a call is hung up the C.O. line does not disconnect until 5 to 8 seconds later. It seems like a long time before it disconnects. Is there as setting I need to adjust. Any thoughts would be appreciated.

The provider is Comcast phone modem.
Thanks in advance.

Comcast may not be providing disconnect supervision. You should check your DISA retry counter and set it for 0. Also there is a CPT function which when enabled will allow the Summit to disconnect a co line when encountering an error tone.

Thanks Derrick

I will take a look.

Have a great day!

DISA Retry counter is set to 0 under program 146. I have looked under CO line Data PGM 140 and PGM 141 I do not see anything called CPT. If you share PGM number and I will look at it remotely.
I will also call Comcast Monday and see if they have Disconnect Supervision turned on?

Any further advise would be helpful. I am an old Nortel tech and C.O. Line Supervision was a program that was turned on if voice mail was installed. But I see nothing like that in the Summit.

Thanks for your time. I really do appreciate it.

Have a great weekend

Pgm 141 Analog (co) attributes. If you use the admin software search function you should be able to find it. The function is actually called line drop (cpt).

It's Comcasts problem and they are aware of it but won't do anything about it unless you press them. However when they make the change it will only work until their modem loses power.
