This section describes miscellaneous E-SBC configuration.
4.14.1 Step 14: Configure Call Forking Mode
This step describes how to configure the E-SBC's handling of SIP 18x responses received
for call forking of INVITE messages. For the interoperability test topology, if 18x with SDP
is received, the E-SBC opens a voice stream according to the received SDP. The E-SBC
re-opens the stream according to subsequently received 18x responses with SDP or plays
a ringback tone if 180 response without SDP is received. It's mandatory to set this field for
the Lync Server 2013 environment.
To configure call forking:
1. Open the General Settings page (Configuration tab > VoIP menu > SBC > General
Settings).
2. From the 'SBC Forking Handling Mode' drop-down list, select Sequential.
