Changed sdp_session option in the pjsip.conf but it didn't work

[silentwatch]

Hi there,
I tried to change the “sdp_session” option in the “pjsip.conf”, but when i saved the configruation and performed a call, it seemed like that the “s=” was still “s=Asterisk”, not “s=test” which l changed in the “pjsip.conf”. I am sure that i changed it and saved it.
Any ideas?

Please share with us what you changed and unfer which settings/field

And also whether you reloaded Asterisk.

Thanks for reply.
My version of the asterisk is 16.16.1, which is installed in debian 11 by apt.
I have two hosts connected through the pjsip wizard. The settings are follows:
[trunk_defaults](!)
type = wizard
transport = transport-udp
endpoint/allow_subscribe = no
endpoint/allow = !all,ulaw
aor/qualify_frequency = 30
registration/expiration = 1800
registration/contact_user = tests
endpoint/contact_user = tests

[trusted-peer](trunk_defaults)
endpoint/context = tests
remote_hosts = <IP>
sends_registrations = no
accepts_registrations = no
sends_auth = no
accepts_auth = no
contact_user = tests

In “pjsip.conf”, i changed these settings:
[transport-udp]
type=transport
protocol=udp
bind=0.0.0.0

[endpoint]
rtp_engine=test
sdp_session=test

[global]
user_agent=test
default_from_user=test
default_realm=test

Did some of these settings are conflicted?

Thanks for reply.
Yes, i tried to reload module(res_pjsip.so), system(command reload) and the os(command reboot), but all of these action didn’t work for me.By the way, only “sdp_session” option didn’t work, and the rest works.

There’s no conflict, but you haven’t really configured things. There’s just a random category named “endpoint”. If you’re using wizards, you also can’t change things in pjsip.conf for it. You change it in the wizard configuration instead on the specific entry.

I see… So the “[endpoint]” section in “pjsip.conf” is just some help documentation for setting it?
I set “endpoint/sdp_session = test” in the “pjsip_wizard.conf” and it worked. But there were something wierd happend, let me use this picture below to explain it.

So, when i performed a call, the INVITE from asterisk A to asterisk B contained the “s=test”(same when from B to A), which worked well. But the INVITE from asterisk to softphone is still “s=Asterisk”, which really confused me. Is there any other settings to change this? Or maybe this is protocol problem which can’t be changed?

endpoint will be a meta name. That part of the sample is trying to list all possible options, but the realistic content of the section, which actually would include a type=endpoint line, is given earlier.

Personally I find it much easier to debug configurations if the wizard isn’t used.

The soft phone is a different endpoint. The wizard.conf your gave above only has settings for trunks.

[jcolp]

Each endpoint configuration is independent. You probably set it on one, but not another.

Thanks for your reply.
Yes, my softphone endpoint is defined by realtime database, after i updated the sdp_session column, it works very well. Your answer also solved my confusion about setting asterisk, thank you very much.
Have a good day!

[silentwatch]

Yes, you are right, i forgot to change the softphone endpoint. Thanks for your help!
