SIP Session Timer
● Use RFC 4028: RFC 4028 defines an expansion of the Session Initiation Protocol (SIP).
This expansion allows a periodic refresh of SIP sessions. The user agents and the proxies
can use the refresh to determine, whether the SIP session is still active.
● Session Expires (sec.): Defines the longest duration of an SIP session. The recommended
value is "1800". If possible the figure should not be below this value
● Minimum SE (sec.): Defines the shortest duration of an SIP session that is allowed (spec-
ified in seconds). The smallest value allowed is "90". The value "90" is also the default val-
ue.
Provider Calls
● Maximum possible number of callers via provider: Number of simultaneous calls via all ac-
tivated providers. The maximum number depends on the data rate to the Internet and the
codec used.
Scenario: A number of trunks, e.g. 2 is created for each activated provider, which would
produce a figure of 8 trunks for 4 activated providers. If however the bandwidth is only avail-
able for 4 calls, then these parameters prevent a 5th call being set up and thereby a dis-
ruption to the payload.
