what am I missing please? autoload is set to yes in modules.conf

dzavy · December 30, 2016, 8:15pm

Any ideas? Looks like some sort of circular dependency, I don’t think there’s a module missing.

The only pjproject module I’m able to load is res_pjproject.so.

For the “embedded” pjproject I noticed there’s a set of patches, do they also need to be applied on the “external” pjproject sources?

jcolp · December 31, 2016, 2:23pm

The patches are not required. They are backports from PJSIP for bug fixes that have not yet gotten released by them.

As for the load problem it should be res_pjproject.so, then res_pjsip.so, then res_pjsip_session.so, then everything else. The module loader should resolve these automatically.

What distribution are you using?

To me it looks like res_pjsip.so depends on res_pjsip_session.so and vice versa?

It’s crosscompiled for OpenWRT - standard x86 with glibc though, nothing exotic. Everything else is working absolutely fine including codec_opus or 3rd party modules like chan_dongle.

jcolp · January 3, 2017, 12:16am

That would be this issue[1] then.

Great thanks, that was really helpful! Looks much better after applying the patch.

OK now I’m having another issue:

jcolp · January 4, 2017, 3:28pm

What precisely is your configuration in pjsip.conf?

dzavy · January 4, 2017, 4:50pm

Just the absolute minimum:

[system]
type = system

[global]
type = global

[transport-udp]
type = transport
protocol = udp
bind = ::

[transport-tcp]
type = transport
protocol = tcp
bind = ::

[transport-tls]
type = transport
protocol = tls
bind = ::
cert_file = /var/ssl/asterisk.crt
priv_key_file = /var/ssl/asterisk.key
method = tlsv1

[transport-wss]
type = transport
protocol = wss
bind = 127.0.0.1

[1234]
type = endpoint
context = internal
disallow = all
allow = alaw
aors = 1234
auth = 1234

[1234]
type = aor
max_contacts = 1

[1234]
type = auth
auth_type=userpass
password = 1234
username = 1234

Somehow it’s not segfaulting anymore now (didn’t change anything as far as I know)

after adding

transport = transport-udp

into the endpoint definition it seems to be working now

*CLI> pjsip qualify 1234
Sending qualify to endpoint 1234
 contact sip:1234@192.168.88.22:5061
*CLI>

If this is expected then the info here is wrong https://wiki.asterisk.org/wiki/display/AST/PJSIP+Configuration+Sections+and+Relationships (for the endpoint section “transport=” option, if no value is assigned then Asterisk will DEFAULT to the first configured transport in pjsip.conf which is valid for the URI we are trying to contact).

jcolp · January 4, 2017, 4:51pm

You can’t bind a single transport to both IPv6 and IPv4 like that. You need to create two transports, one for IPv4 and one for IPv6. As it is it is creating an IPv6 one and thus there is no transport to send an IPv4 request out on. It certainly shouldn’t crash as a result of that for the qualify like that so file an issue[1].

[1] https://issues.asterisk.org/jira

dzavy · January 4, 2017, 5:21pm

Ah ok, now I see, that’s what 0003-r5403-pjsip_IPV6_V6ONLY.patch is for.

https://issues.asterisk.org/jira/browse/ASTERISK-26309 - so in short IPv6 is not production ready in 2.5.5

jcolp · January 4, 2017, 5:24pm

You have to create separate transports regardless, that’s not going to change. PJSIP fundamentally works that way. On the Asterisk side work has been done to properly support dual stack. The latest releases support this.

jcolp · January 4, 2017, 5:27pm

To clarify in regards to the patch: it made it so that you could create a transport and bind it to “::” to listen on IPv6, without knowing the IPv6 address of the system. Using this you can create two transports - one bound to “::” and one bound to “0.0.0.0”

dzavy · January 4, 2017, 5:37pm

Yep understood - 2 separate transports is not a problem, not being able to use [::] is a major pain though.

Thanks for your help.
