Conference Calls
A conference call is a conversation involving two or more remote parties. To start a conference, there must
be at least two calls and with at least one of them in the
Connected
state and the other in the
Holding
state.
Your system supports two methods to conference multiple parties:
●
Local mixing/bridging
●
External conference bridge
Local Mixing or Bridging
After starting three-way conference calls, you can see the two remote parties in the
Connected
state.
External Conference Bridge
You can connect only SIP or SP calls with an external conference bridge. When using an external
conference bridge, the conference bridge limits the conference size. Check with your conference service
provider on the conference size limit.
Enable an External Conference Bridge
You can configure the conference bridge and enable it as follows.
To enable an external conference bridge:
1
On the
Voice Services >SPn Service > Calling Features
page, enter the user ID or (SIP) URL of
the external conference bridge in the
X_ConferenceBridge
parameter.
2
On the
DECT Wireless – HandsetX – Calling Features
page, set the
UseExternalConferenceBridge
parameter to
True
.
X
refers to the handset’s number.
Note that only participants on the same SP service or using the same ITSP profile as the conference bridge
can be referred to the bridge. For participants that are referable, your system keeps them in the conference
using local mixing. They’re then subject to the local mixing limit.
The Opus codec doesn’t support three-way calling with both legs using Opus.
