Screeching Noise On Transfer

[TheCardMan]

I have a Partner ACS 7 with the Latest Partner Messaging Module (R7) and a 4 Port Card. I have one station, x17, in the Partner that is remote call forwarded to an outside answering service (F11 17 80). At night when you listen to the auto attendant and select "0" to reach an emergency operator, the call is programed to go to ststion 17 which is forwarded to the Live Answering Service. The forwarding works fine but in the process of transferring to the answering service you hear a loud screech for about 1 second and the calls continues to transfer and ring the answering service.

How can I get rid of this screeching? I already replaced the ACS7 processor with a new one and the same thing stills happens.

Any thoughts?

Line current may be too high. It should be in the range of 25-30 mA.

We had the same problem with one. A call to Avaya got us several line attenuators free of charge to solve the problem.

They also have a patch to solve the issue but it did not work on the system we had trouble with. Only the attenuators did the trick.

Thanks for the info. How so I measure the line current? Can I get these attenuators at radio shack? It is a brand new ACS R7, not sure of the software level but I heard of issues with them all.

Attenuators are the preferred way to go, but in a squeeze, you can use 1/2 watt resistors to reduce line current. You would need 2 resistors of similar value. You would wire one in series with the tip and other in series with the ring.

does this happen on all lines using the transfer

if no, swap the lines, and see if it follows the line or the port.

if port, switch to an open line port, if line, test the line like above.

also check your connections between system and dmarc, if follows line. easy way to do this, swap lines at the dmarc, leaving the other connections in tact, to use a different path.


might be better to start there, than buy equipment.
