Ray Crumrine commented on ASTERISK-29603:
-----------------------------------------

I discovered today after some simple testing that setting the *PJSIP_INV_SUPPORT_TIMER* flag *may* not be necessary as operation  *appears* to be normal without setting that bit. No negative effects were observed. I was unable to find any documentation on pjlib Git that stated one way or the other.

>          Components: Resources/res_pjsip

>            Severity: Major

> When using pjsip.conf option "timers=always", asterisk function "timers_handler" does not set complete flag information before calling pjsip and as a result pjsip does not go into the uac mode and does not send sip UPDATES or re-INVITES.
> The "required" state needs flag settings (PJSIP_INV_REQUIRE_TIMER | PJSIP_INV_SUPPORT_TIMER)
> the "always" state needs flag settings (PJSIP_INV_ALWAYS_USE_TIMER | PJSIP_INV_SUPPORT_TIMER)
