PJSIP setting timer_t1 and timer_b


I need to change my t1 timer to 1 second instead of 1/2 second as well as the timer_b setting to 64000 instead of 32000.

I tried adding this to pjsip_custom_post.conf, but it was never applied.

How is this be changed and have it be persistant?

Hi Stewart,

That definitely got me in the right direction, thank you.

My problem was it should not be under [global] but instead [sysetem]

root@freepbx:/etc/asterisk# cat pjsip_custom_post.conf
