I have a Polycom Soundstation phone (older model with no caller ID screen) and it's plugged into an analog line. After I plug the phone in, I can make the first call just fine. But after I hang up from the call, the phone won't release the line! I can't make another call unless I totally unplug the phone & plug it back in. Any help? Thanks!

SOURCE: Conference call with a Polycom SoundStation EX

The conferencing capability to bridge 2 (or more) external stations comes from the telephone equipment/service that you have purchased. Either you are behind a PABX or Electronic KSU, which provides multiple phone service to your office, or you purchase conferencing capability from your local telephone provider (Verizon, AT&T, etc). In either case, the way to initiate a conference call would be the same as when you would have a desktop/office phone and establish a conference/bridged call to external parties. Usually this occurs by having one party on the line, flashing the disconnect button momentarily, getting a new dial tone, dialing and connecting to a second party, then flashing the disconnect button again, which signals the equipment to bridge those two calls to your station.  On the SoundStation EX there is a Flash button that provides that capability of momentarily flashing the disconnect button.  Try and see if that works. If not, then you will need to make arrangements to purchase the external equipment or service from your provider.  If you have the PABX or electronic KSU, it may also be a configuration option that you will need to have your support person for your telephone system, activate for that station connected to the SoundStation EX. Hope that helps.

I thought well I wonder what holding down other buttons would do to get rid of this cursed PLEASE WAIT issue.
I tried * and # together and hey presto it worked.
I did however have to go in and turn IP mode off.
