Published Option
sip-link-type
Default Value: 0
Valid Values: 0, 3, 4
Changes Take Effect: After SIP Server restart
Specifies whether SIP Server will run in multi-threaded mode, or in single-threaded mode for backward compatibility. Configure the valid values for this option as follows:
- 0 (default)—SIP Server runs in single-threaded mode, as in pre-8.0.3 releases, with the Main thread processing T-Library requests, distributing Events, managing SIP calls, and processing SIP signaling
- 1,2—Reserved for debugging
- 3—Enables multi-threaded mode with the following threads:
- T-Server thread—processes T-Library requests and distributes Events
- Call Manager thread—manages SIP calls and processes SIP signaling (except OPTIONS messages)
- Service Checker thread— performs Active Out-of-Service Detection (OPTIONS messages)
- 4—Enables multi-threaded mode designed for IMS double-dip deployments, with the following threads:
- T-Server thread
- 16 Call Manager threads
- Service Checker thread
- Presence Manager thread
In both single-threaded and multi-threaded modes, SIP Server runs the following threads:
- SIP transport layer thread to dispatch SIP messages
- Operational Information thread to collect and report statistics; to perform NIC monitoring
- A number of auxiliary threads
Important: For an HA configuration, this option must be set to the same value in both primary and backup SIP Servers.
