Provisioning Session Timers for SIP Subscribers

The system uses session timers to periodically refresh SIP sessions during call processing or in-progress calls. You can enable or disable session timers for calls to and from all SIP subscribers on the BTS 10200 through the SUB_SESSION_TIMER_ALLOWED parameter in the ca-config table. They are disabled by default.

Use the commands in this section to provision session timers for SIP subscribers. Session timer defaults for subscribers are defined by internal defaults. They can be adjusted through the commands shown in this section.

Note For a detailed description of session timers, see “SIP Session Timers” section on page 4-7

Step 1 Adjust the session timer values in the sip-timer-profile table.

Note The session duration field value is in seconds with a range of 100 to 7200.

The minimum session duration field value is in seconds with a range of 100 to 1800.

We recommend a value of at least 1800 for each of these fields.

add sip_timer_profile id=<timer_profile_id>; session_expires_delta_secs=7200; min-se=1800;

Step 2 Enable session timers for SIP subscribers:

add ca-config type=SUB_SESSION_TIMER_ALLOWED; datatype=BOOLEAN; value=Y;

Step 3 If not already done, add a default sip-timer-profile-id to the ca-config table:

add ca_config type=SIP_TIMER_PROFILE_ID; datatype=STRING; value=<sip_timer_profile_id>;

SIP Timer Values for SIP Subscribers

Note This section describes how to provision SIP timer values for SIP subscribers. For a comprehensive listing of SIP timers, see Chapter 4, “SIP System Features.”

You can customize SIP timers through the sip-timer-profile table. A record in this table can then be configured to apply to all subscribers switch-wide. The system operates with default SIP protocol timer values, as noted in the SIP specification. These default values are adequate for many installations. If customization is required, a sip-timer-profile table can be provisioned and associated with all calls.

Use the following steps to provision the SIP timer values.

Step 1 Adjust the SIP timer values in the sip-timer-profile table if necessary (example shown).

add sip-timer-profile id=<timer_profile_id>; timer-t1-milli=500;
