Call setup version at network Call Back

This command specifies which version of call setup is used at execution of network Call Back towards an ISDN network.

Version 1: |  | A transmission path between originating and terminating PBX is established and the called party reserved, before the initiating party is called. When the initiating party answers the call, the party in the terminating PBX is called.

Version 2: |  | The initiating party is called and when it answers a new call is set up to the called party.

For version 1 UUS (User to User Signalling) services 1 and 2 have to be supported by the connected ISDN network, for version 2 UUS (User to User Signalling) service 1 is enough.

All PBXs in a same private network, where the use of network Call Back is allowed, must have the same call setup version for network Call Back.

Note

If the private network is an MD110 BC10 network (see command 2072 MD110 release version of CN) then version 1 is not available and version 2 has to be used.

Values:

0 = |  | Version 1

1 = |  | Version 2
