Vendor denying need for reliable disconnect

Vendor denying need for reliable disconnect

Vendor denying need for reliable disconnect

Our Operations group is working with a reseller to get better rates on some of our phone lines. I've indicated to them that our IPOs need reliable disconnect and given them documentation. They have consequently met with the Operations group and told them that we have no need for reliable disconnect. Since the actual last mile carrier hasn't changed the systems that already have the feature are working fine. Going forward with new service however they provider (reseller) will claim that RD doesn't exist and that we don't need it.

Since I've already provided them proof from the avaya documentation does anyone know of an authoritative source on reliable disconnect that they might believe if I presented it to them?


RE: Vendor denying need for reliable disconnect

Maybe they don't understand the feature. It is often called "disconnect supervision" or "disconnect drop pulse". If you don't have voicemail, you don't need it. But since most folks DO have voicemail, it is fairly mission-critical.

RE: Vendor denying need for reliable disconnect

even with voicemail it will not cause your trunks to lock up under normal operations as the voicemail will time out usually, just if you use trunk to trunk transfer as then there are two trunks and if both don't disconnect they stay connected until the power goes out.
mforrence is right with the terminology different providers use different lingo and sometimes the people you talk to in sales have no clue what it is as it is a strictly technical spec that is on the line.

RE: Vendor denying need for reliable disconnect

Thanks both of you for your responses. I'm aware of the different names for the feature and have given them not only several of the names but the definition of the feature as well as the different "flavors" (i.e. <5ma signal or tone). After showing them in the Avaya documentation that it was necessary they came back with the premise that it was an "antiquated" feature and no longer used or needed.

Westi, I have had multiple systems that had voicemail issues because reliable disconnect wasn't enabled, both IPO and the older Avaya Distributed Office systems. The RD is essential for proper operation with voicemail.

Thanks again,
Joe M.

If the provider has a DMS from nortel, the feature is called COD( cut on disconnect).

if it ain't broke don't fix it!

DMS-10 it is called "LPDS" - just went through this with Verizon in a rural area that used to be Continental Telephone
