MRF SIP persistence records are deleted after updating the timeout value with the iRule 'SIP::persist timeout'.
Connections are not persisted as expected, causing additional processing, load balancing, and potential for misrouted messages.
-- MRF SIP configured with a persistence mode enabled. -- Persistence timeout value is modified with iRule 'SIP::persist timeout'.
Do not use 'SIP::persist timeout' to update timeouts. Increase initial timeout values when using custom persistence mode or switch to a non-custom persistence mode that updates timeouts automatically without iRules.
The iRule 'SIP::persist timeout' no longer causes the persistence record to be deleted when updating the timeout value.
