Initiating a new SIP session for redirected SIP calls
Normally, if a SIP call is redirected to a different location by receiving a SIP 3xx response, only the request
header is replaced in the original INVITE message and the INVITE is sent to the new destination. Using the
following procedure, the SIP gateway can be forced to create a completely new session for forwarded calls.
Mode: gateway sip <gw-name>
Step
1
[ name ] (gw-sip)[ gw-name ]# [no] new-
session-after-redirect
Enabling the SIP penalty-box feature
The following command enables the SIP penalty-box feature, which causes a non-responsive server not to be
contacted again for the specified duration. A server will be in the penalty box for the specified time as soon as a
single transaction with that server fails.
Mode: gateway sip <sip>
Step
1
[ name ] (gw-sip)[ gw-name ]# penalty-box-
time <seconds>
Disabling SIP transport protocols
The following command disables one of the SIP gateways transport protocols. Some SIP servers do not sup-
port TCP, only UDP. In this instance you would disable the TCP transport protocol.
Mode: gateway sip <sip>
Step
1
[ name ] (gw-sip)[ gw-name ]# no transport
{tcp|udp}
