Hello, The DNS SRV working when phone is registering ("Registration URI" need 
to be empty)

When try to make call, the invite message send to first (down)server and call 
failed (408)

Csipsimple 1.01.00 r2272

With "registration uri" empty the app will not register at all to the sip 
server. So by removing the registration uri you might have hidden some initial 
problem.

Then about the 408 it's usually about a connectivity problem. So my first idea 
is to suspect that what's returned by the dns srv resolution points to an 
invalid ip/port that cannot be reached from the network you are connected to.
Without more details about your sip server domain so that dns config can be 
checked it will be hard to help, but I can confirm that dns srv feature is 
working properly with properly configured dns srv domains.

Hello, I have two opensips proxy servers. I tested with Bria and Zoiper and all 
is working whitout problems. I see that csipsimple add to sip message "Route" 
option...

If you don't want pjsip (the stack behind csipsimple) to add the route header, 
add ";hide" at the end of the proxy uri (without the double quotes).

If your sip server fails when sip client indicates the route it's probably 
because your sip server does not resolved dns-srv and realize it's himself. 
(and probably as consequence it fails to re-route the reply to the sip client, 
and that's why you get a timeout). This header is in standard and sip server 
properly configured should not be lost if the route header is added.

great :-) 
I sill advise you to check your config on server side however. CSipSimple 
relies on pjsip stack which is one reused in many other projects. some of the 
other projects does not gives as many tweak options than CSipSimple. So you 
might find this problem impossible to solve with other sip clients.
Also pjsip stack was announced to be the sip stack of next version of Asterisk 
servers, so in future you might find also problems if you do trunking with 
other servers (pjsip is a very serious, robust and rfc strict implem of sip)
