[SR-Users] Intermittent delays relaying BYE (up to 1s)

[Alex Balashov]

You’re very welcome! 

It may be that the DB operation for BYEs is different in nature and more latent than for INVITEs, as odd as that would seem.

If the inherent latency of the operation is unavoidable as a matter of technical design or insurmountable realities of server performance or whatever, there are various ways to make such operations asynchronous — that is, to send them to be performed by a separate pool of worker processes unrelated to the main SIP message worker processes.
