Sip Bla Expires Timer - Aastra CT9143i Release Note

SIP BLA Expires Timer

Release 2.3 now includes a SIP BLA subscription period parameter that allows an Administrator
to set the amount of time, in seconds, of the BLA subscription period.
If this parameter is set to zero (0), the phone uses the value specified for the BLA expiration in the
subscribe message received from the server. If no value is specified in the Subscribe message
received from the server, the phone uses the default value of 300 seconds.
You can configure this parameter using the configuration files or the Aastra Web UI.
