Hello All,
I read “Module that implements publish and subscribe support” on wiki.asterisk.org (link below) but I can’t add in pjsip.conf.
Do you have an example config about adding subscription_persistence option in pjsip.

It’s not an option you can set, it’s always done. That just details the information it stores for each subscription.
