YASS

OK, I found the way for PJSIP to use DNS SRV lookups, but I need you to try it or give me an account to try it :)

You can try it by doing this:

• Close YASS.
• Open YASS configuration db and insert a nameserver to do the lookup (I'll use 4.2.2.1 for example)

saghul@topux:~$ sqlite3 .yass/config.sqlite
SQLite version 3.5.9
Enter ".help" for instructions
sqlite> insert into ua(opt, val) values('nameserver', '4.2.2.1');
sqlite> select * from ua;
max_calls|2
user_agent|YASS - pjsip
stun_host|
nameserver|4.2.2.1
sqlite> .quit
saghul@topux:~$

If it works for you I'll add it tho the GUI so it can be manually configured :)

Thanks again for your feedback!

It does basically nothing. BTW, which is your aim with it? does it set the outbound proxy?
I've added "aliax.net: 91.121.79.216" and later called to "sip:ibc@aliax.net", getting the same error about PJ_ERESOLVE.

Also, why sould such a feature appear in the config box? The bug report is just about the incomplete DNS resolution of YASS, do I miss something?

Please, give more love to this bug as supporting SRV is a more than required feature nowadays for any modern SIP device :)

I expect it shouldn't be so difficult, and sure pjsip handles it by itself (and also failover).

YASS now resolves DNS SRV hostnames :) Please check r171. I did'nt know very well how to check failover, maybe you can describe me what the appropiate setup would be (I've setup a bind nameserver with SRV).

Comments are always wellcome :)

DNS doesn't work for me :(

I send a call tosip:xxxxxx@alaix.net (there is no DNS A entry but just SRV) and it doesn't work). I see nothing in the logs, just a window error "(CALL-001) Couldn't make the call.".

I have just tested it against Aliax server with my user saghul and it's working fine :-O What revision are you using? Did you install python-dns package?

I'm not using a SRV for registration, but for destination (I call from oversip.net to aliax.net and it doesn't work).
Also, I don't understand why python-dns (I have installed it right now) is required. Doesn't pjsip handle SRV by itself (pure C)? or is it handled by pjsua (python)?

OK, I'm registered at my local PBX and called xxx@aliax.net. It worked! Look:

python-dns package is needed for two things: * Loading nameservers from /etc/resolv.conf * Performing DNS SRV queries for STUN, to detect if an invalid host was provided.

Please, remove YASS completely (that includes your home .yass) download from SVN and execute it right there, without making a package. If that works for you the package may be missing some file, it check it now anyway :)

Just made a package and tested again. It's working for me :-O
