External endpoint and dial plan configuration

[jeroenvip]

Hello,

First of all thank you for reading this. We are using asterisk with an external application and a trunk (Twilio). In the dial plan asterisk is communicating with the external application REST API in JSON format which tells what asterisk needs to do.

The pjsip_wizard.conf contains the trunk information

[trunkDefaults](!)
type=wizard
transport=transportSecure
endpoint/allow=!all,ulaw,alaw,G729,G722
endpoint/direct_media=no
endpoint/rewrite_contact=yes
endpoint/rtp_symmetric=yes
endpoint/allow_subscribe=no
endpoint/force_rport=yes
endpoint/media_encryption=sdes
aor/qualify_frequency=60

[twilio](trunkDefaults)
sends_auth=yes
sends_registrations=no
remote_hosts=xxx.pstn.dublin.twilio.com
outbound_auth/username=xxxx
outbound_auth/password=xxxx
endpoint/context=xxxx

The pjsip.conf contains “soft phone” endpoints

[transportSecure]
type=transport
protocol=tls
bind=0.0.0.0:5061
cert_file=/etc/letsencrypt/live/xxxx/fullchain.pem
priv_key_file=/etc/letsencrypt/live/xxxx/privkey.pem
external_media_address=xxxxxx
external_signaling_address=xxxxx
method=tlsv1_2
verify_client=no
verify_server=no

; softPhones
[local1]
type=endpoint
transport=transportSecure
context=xxx
allow=!all,ulaw,alaw
aors=local1
media_encryption=sdes
rtp_symmetric=yes
;direct_media=no
;disable_direct_media_on_nat=yes
;force_rport=yes
;ice_support=yes
dtmf_mode=rfc4733
rewrite_contact=yes

[local1]
type=aor
max_contacts=1
remove_existing=yes

[local1]
type=auth
auth_type=userpass
password=local1
username=somesuperduperpasswordhere

Question
What is the best practise to create a dynamicly configured pjsip.conf file with which can change once in a while ? ( Already checked this out, Setting up PJSIP Realtime - Asterisk Project - Asterisk Project Wiki But all the logic is not happening in asterisk itself, its done based on external output)

Something like this?
Run a script (shell script) every x minutes that repopulates the pjsip.conf file with all the up-to-date end points. And preform a core reload (asterisk -rx “core reload”) to enable the most up-to-date pjsip.conf file.

Question
Is it safe to preform a core reload while calls are running ?

[TheMark]

well what do you need to change and why, also how often is “once in a while” every 1 min or every 10 day
yes “pjsip reload” is safe to run while calls are active
also remember to make your reload script, so it only reload if there is changes

Some options will not actually have an effect until there is a restart, and some options may be cached for the session. I’d think I’d only want to say it was safe for calls not using something that is changing, to be on the safe side.
