Teleph Telephone Call

NOTE SOME SYSTEMS AND SOFTWARE VERSIONS AND NETWORKS DO NOT SUPPORT ALL BANDWIDTH SELECTIONS.

Choose the preferred quality by selecting the desired call rate in the ‘Call Rate’ field.

You may also press the ‘Set as Default’ Quick Key in order to make the selected bandwidth the default bandwidth for subsequent calls.

Set ‘Set Restrict (56k)’ to ‘On’ to make a restricted call. An indicator ‘(56k)’ will be shown behind the number.

TIP

RESTRICTED CALL A RESTRICTED CALL IS A CALL TO A 56 KBPS NETWORK. BY DEFAULT THE SYSTEM WILL DIAL AN UNRESTRICTED CALL (A CALL TO A 64 KBPS NETWORK) AND DOWNSPEED TO 56KBPS IF NECESSARY. TO FORCE A RESTRICTED CALL, SELECT ‘SET RESTRICT (56K)’

TIP

DIALING TWO NUMBERS

SOMETIMES (ESPECIALLY WHEN CALLING TO AND WITHIN NORTH AMERICA) IT IS NECESSARY TO DIAL BOTH ISDN NUMBERS WHEN MAKING A VIDEO CALL USING 2X64 KBPS OR 2X56 KBPS. SELECT ‘128’ IN THE QUALITY MENU. WHEN YOU RETURN TO THE DIAL MENU, BOTH ‘NUMBER:’ AND ‘2ND:’ ARE DISPLAYED. ENTER THE SECOND NUMBER.
