Using the ISDN Gateway.

Calling out
You can make calls to other ISDN Videoconferencing units as follows.
Select the Video Call box on your Polycom Viewstaion and hit the call button on your Polycom remote. This will bring up the Videophone screen.
Enter your ISDN number, for example the Global Leap Test number is 02084262194
Next scroll down to next box of the Video phone screen below the above number and on the left. Hit the Polycom remote control select button (the RED button) you will find this box toggles to AUTO or IP or ISDN, you need to select AUTO. Go to the next box to choose the speed of the ISDN call to your destination. This will typically be 2 x64 or 128.
2 x 64 is for unbonded ISDN calls. We have found that this is required if you wish to connect to Videoconference units used by Moorhouse Black. For any other types of units use 128. If your destination VC unit supports greater speeds choose the appropriate speed up to 384. Hit call to complete the call. Remember you will be paying for this call.

For more advanced users we have a short cut for ISDN dialing.
To make an ISDN call, just select the video call box on your PolyCom unit.
Enter 81 followed by your ISDN number for a 2 x 64Kbps ISDN call, choose IP and speed of 2 x 64. Press the cal button to make the call.
As above enter the prefix 82 for a 128Kbps ISDN call, a prefix of 84 fo a 256Kbps ISDN call, and a prefix of 86 for a 384 Kbps ISDN call.

Some examples:- To connect to the Global Leap test site, their ISDN number is 02084262194. To make a ISDN call enter 8202084262194 in the vide call box on your PolyCom unit, select IP and a speed of 128. Then select the call button to make the call.
