Detailed Description
Tab. 178 Variable and preconfigured conference
Notes:
– If the conference tone is deactivated in the system configuration, a
conference participant who is intruded upon will not hear an attention
tone. Observe the national data protection regulations. With a three-
party conference in the public exchange, the signalling depends on
the network provider.
– Variable and preconfigured conference:
If a user is redirected or if he has activated CFNR, he will not be
included in the conference. In a preconfigured conference the confer-
ence participant in question will be removed temporarily from the
conference group. The External priority parameter is not taken into
account.
On the systems A150/300 and 2025/2045 a maximum of 3 three-party conferences
and 1 six-party conference are possible simultaneously on the PBX.
On the system 2065 a maximum of 10 three-party conferences and 4 six-party con-
ferences are possible simultaneously on the PBX.
