H.221 or 2x64 (2x56) Calling

Some older or low end video systems do not have the ability to make bonded ISDN calls. In these cases it is necessary to dial both ISDN numbers separately to call those systems.

These types of calls are often referred to as

H.221 calls

2x64 calls

2x56 calls

-as making 2 x 64 kbps or 2 x 56 kbps calls to the same system. Place this type of call by:

Set Network to ISDN

Set Bandwidth to 128 kbps

A field for the 2nd number pops up in Call Settings.

Enter the second number in the Call Settings field. For 128 kbps calls that use bonding, ignore the second number field and just enter one number to be dialed.

Using sub-address / extension address / MCU password

Sub-address is used to address different systems on the same ISDN line and is primarily used in European Countries. LAN equivalent extension address or TCS-4 is used to address different systems on a LAN, when dialing via a gateway.

To specify an ISDN sub-address or its LAN equivalent extension address (TCS-4), add a star (*) after the number and then enter the sub-address/extension address.

Example:

12345678*10 ( <number>*<Sub-address/extension address/MCU password>)

When dialing IP via a gateway, the number behind the star (*) on IP might be interpreted as an extension address.

When calling to external MCUs requiring a password (TSC-1), this password can be added after the star (*). If no password is specified, the user will be asked to enter the password (after connecting to the MCU).
