CPC (Release Supervision) and the 200ICP

[MitelInMyBlood]

I realise this is a known problem, but am curious if anyone has come up with a workaround.

We have a number of SX200ICP deployed in remote rural areas with POTS service furnished by "Lum-N'Abner's" Telephone Company. Unfortunately these little mom'n'pop telcos haven't a clue when you tell them you want CPC (momentary open) from them when the caller hangs up. The problem is when calls hit the auto attendant they never clear down and wind up tying up one or more (or eventually all) of the precious few outside lines in these locations.

In the city it's not a problem because the RBOCs understand (and furnish) CPC. So what are y'all doing for this problem out in the sticks?

Boy talk about timely thread, I'm sitting here waiting for Embarq to get back with me about this problem I am having with a 200 EL, I have been going around on this for over two weeks now. seems they would be big enough to figure this one out, they say it has been applied to my "pots" trunks but I can put a meter on the line and do not see any change on disconnect. At least they are trying........

I've never dealt with this problem, but have seen CPC generators, in case that helps:

The CPC-1 will generate a CPC disconnect signal on a PABX analog station (or any other line that does not provide this signal).

Are they not returning dial tone after a while? EMEM should detect dial tone and disconnect. It's built-in and not modifiable.
