Issue Dialing to PSTN from SoundStation IP 7000

[Anonymous]

Hello all,

I have a SoundStation IP 7000 conference phone on a ShoreTel phone system at my organization (it is the only VOIP conference phone that we have.)  I am experiencing an issue when attempting to place an external call to the Public Switched Telephone Network (PSTN) from the SoundStation.

If I take the SoundStation off-hook by pressing the green off-hook button, I get a dial tone as expected.  I enter 9 to access a trunk line, then begin to dial the ten-digit external telephone number.  As soon as I enter the 9th digit, however, I get a "fast busy" signal.

If, however, I don't first take the SoundStation off-hook, but instead enter 9 followed by the ten-digit phone number on the phone's keypad, then press the Dial button on the SoundStation, the call completes successfully.

Calls placed from the SoundStation to internal four-digit extensions work successfully either way.

I notice that when I take the SoundStation off-hook and press 9, the dial tone goes silent, whereas when doing the same thing with any other ShoreTel extension, you hear the dial tone when you pick up the receiver, and a slightly different-sounding dial tone right after pressing 9 to access an outside line.

There must be some configuration setting in the Polycom or ShoreTel system that is causing this, but I have no idea as to where it might be.  Can anyone offer any suggestions?

Thanks in advance.
