23 Configuring FXS Port Transfer Behavior
Since the Mediation server does not support receiving SIP Refer messages, you must
configure the Enhanced gateway FXS port to send INVITE messages (in the event when
call transfer is initiated from the FXS port).
Note: For this feature to work, an MPM module is required, and media channels should
be configured according to the number of FXS ports (see below).

To configure the FXS port transfer feature using the re-invites parameter:
1. Open the Advanced Parameters page ( Configuration tab > VoIP menu > SIP
Definitions > Advanced Parameters ).
Figure 8-34: Enable Call Transfer Using Re-invites
2. From the 'Call Transfer using re-INVITEs' drop-down list, select Enable .
3. In the 'Number of Media Channels' field, enter the number of media channels; two
media channels for each FXS port.
