Sessions and Media
Here, settings are made for the SIP timeouts and sessions negotiated via the Telecommuting
Module.
Note that no DTMF settings are needed in the Telecommuting Module.
Session Configuration
Session timer
Enter the maximum time for a SIP initiated connection. When the timeout is reached, the
Telecommuting Module discards the media streams. The clients won’t notice, as the con-
nection is still active, but you won’t hear anything as no media streams are let through. To
avoid this, clients can regularly ask for new timeouts.
The Session timer must be at least 90 seconds to comply with the Min-SE requirement (RFC
4028).
Timeout for SIP over TCP/TLS
The Timeout for SIP over TCP/TLS decides how long a SIP connection over TCP with
the Telecommuting Module may exist without having received a complete SIP request.
