V3001 Analog Outgoing Calls 1 Ring Then Disconnect

Hello,



I am having problems on a new install of a V3001 analog. On outgoing calls, it will ring once then disconnect. The phone company (Cablevision) says they are seeing a disconnect notice coming from the NBX. The NBX says it is receiving a disconnect from telco.



any help is much appreciated.

Does it do the same if you hook an analog phone to that line?

No, they hooked a buttset up to it and dialed out successfully.

It's not the same, among other things, the impedance (for example)of the phone it's diferent acording with the equipment you use and that make a huge diference, try to do the loopback test vcxguru68 is sugesting, it's simple, connect the ATA port to a Analog Port, then call to the ATA and check if you get disconnected. If not you just probe the hardware part of the v3001 is working just fine. If this still happen check gains in audio setting and put them in default values.

Are you running NBX 6.5.18? if so, this is a known issue and you should contact 3com for a patch.

Hey Bosoxfan,



We had a call into 3com about this and they sent us the patch about 15 minutes before you posted. Your help is very much appreciated.

To recap for the next guy with this problem:

V3001 Analog running 6.5.18 - Incoming calls work fine, outgoing calls ring once or twice and then disconnect. Status of the line card shows a disconnect for that call.

Patch name = NBXV3001A-PATCH-R6.5.18-cms0687527.taz



We spent 3 days blaming the provider and making them switch out their equipmnet. The worst part is having to admit that the cable company was right.
