disconnect on loop start lines

[cilcomm]

I have a few sites that have POTS lines and they are using a Call Pilot or an old Flash for voicemail. The calls that hang up in middle of the main greeting are routing to the attendant as "ghost calls" because the CICS or MICS is not seeing the hang up. I have tried adjusting the Disconnect timer in "maint" programming but no luck on "seeing" the hang up. When I have called the LEC (Verizon), They act like they have never heard of Disconnnect Supervision or CPC pulses or anything that will signal my switch on a loop start line that the incoming caller has hung up. Has anyone in the Central Illinois area on a Verizon CO had this problem and what can I tell them to get the right feature for the this turned on? I tried to tell the Verizon salesperson this but they have no clue what feature or option it might be that we can have turned on or whether it is a billable item for the customer.

The basic jist is that the customers are tired of getting ghost vcalls to the attendant and blank 45 second messages in the general mailbox at night. I need a solution other thatn converting to Ground start trunkks.

Sandman sells a product if you cannot get it from the CO

I usually have to go higher than sales guys to find someone who knows what disconnect supervision is. I am not in your area, so I cant speak to it specifically, but the only times I have not been able to get it on loop start lines is when the dial-tone is provided over a T-1 with a channel bank. But in that case you can switch over to ground-start. Are your lines running through a channel bank?

You can actually hear the CPC pulse. Listen to a POTS line with a butt set and approximately 1-2 seconds after the remote party hangs up you will a distinct click or hum lasting about 1/2 a second.

is it just the vm or is it all calls..including with butt set???

6 months until ski season starts...sadly i must resign myself to the warmer weather"this will include a normal 8-5 work day, 5 days a week"

It is not running through a channel bank. Channels running through a T-1 channel bank would have the feature already in our area for normal NI2 PRI's. I dont hear a CLick or hum other thatn the far end party's hookswitch click and it is on all calls and not just VM.

I will try to contact the sales peolpple again and refuse to let them tell me no until I talk to a higher power at Verizon.

call in a ticket to repair not sales you will get a resolution much sooner...or tell saleperson you want to order disconnect supervision and 2 spare cans of dialtone for a powerfail condition and spend the day laughing

Not sure what switch is in the Illinois CO, but if it is an old GTD5 EAX switch and your customer has Centranet, then you WILL have disconnect supervision problems on loop-start lines on incoming calls. It seems all the GTD5 EAX switches at least in CA have this problem when the lines are setup in Centranet. It can take up to 45 seconds to get the 'open loop' condition to drop the call. I had this happen when I setup a customer with Autoattendant service on their system and kept getting phantom calls. After testing this is what I discovered. I explained to the customer what caused it so they know what is going on. But no fix from GTE.

These areas are the old GTE areas. The name may have changed but some of the attitudes are still GTE with idiots that are to lazy to find out the info or transfer you to someone that knows what is going on! No excuse! Too much buck passing!

You can find out what equipment the CO has by the NPA-NXX code and looking it up on the Verizon access website or some of the sites that have up-to-date switch info. I don't have the URL at the moment, but you could probably use Google or similar to find it.

Hope this helps!

most of my sites are not centranet but they are still on the GTD5 switch. The local CO has 2 switches running since they are a regional CO as well. The other switch is a DMS switch I think. I have inquired with them what it would take to move a customer from the GTD5 to the DMS and they responded with an answer that basically told me that they have no idea, they wont put forth the effort to find out and since I have dialtone already, It was not a concern of theirs. " I have perfectly acceptable dialtone with no problems ( other than the disconnect) and that was all they had to deliver to me.

I will press on with the search and inquiries with Verizon in Jacksonville, IL.
Thanks for all the replies

That sounds like the old GTE (aka The Giant Telephone Experiment - that failed!)
Some options: you could number change the customer to the DMS or you could escalate the issue to the state public service commission and file a complaint or find another service provider with a DMS or a 5ESS switch that has a known track record for "good" service for your customer. You might throw the service provider change at Verizon to see if they might budge. In some areas the ILECs are paying a little more attention to some concerns because of the line losses they are now seeing with the CLECs.

Sometimes it takes a little persistence with companies like this. But if you have the time and some patience you can usually win or at least get some resolution for the problem.

They can definitely be a 'stick-in-the-mud'. I grew up with this company and have had some very interesting experiences over the last 40 years with them here in California.

Verizon is the only game in town. There are no dialtone resellers like McLeod or Frontier in this area. SBC cant get their foot in the door until they finish buying out the outlying areas that used to be served by this same regional verizon CO.

thanks again

I feel your pain...I have issues with my DS on Verizon in NW Indiana...

If I get it figured out before you, I will let you know.
