hi, i have a new install of freepbx 13 (Asterisk 13.14.0) and about 15 grandstream phones. the phones connect using pjsip/tls and srtp. the phones seem to be working good, but i have noticed that if I make a change (any change) on the pbx that requires me to hit the ‘apply config’ button, all the phones go into a “unavailable state” according to “pjsip show contacts”. at this point, the phones seem fine but the pbx has dropped them and calls go directly to voicemail. the only way I can recover is to reboot all the phones.
applying the config (asterisk re-load config) does NOT drop the sip udp (non tls) connections I have.
I would appreciate help from anyone who has experience with this
thanks for your time!
