[asterisk-users] PJSIP: Failed to create outgoing session to endpoint

[Dmitriy Serov]

Hello.

I am using asterisk and chan_sip a lot of years. And newbie in chan_pjsip.
Now i am transfering all from chan_sip to chan_pjsip. And have a lot of 
questions. First of...

system: Asterisk 13.2 on slackware 14.1
Errors on outgoing call:
[2015-03-03 00:18:58] ERROR[6794]: chan_pjsip.c:1778 request: Failed to 
create outgoing session to endpoint 'srv_d228'
[2015-03-03 00:18:58] WARNING[24528][C-00001bcc]: app_dial.c:2431 
dial_exec_full: Unable to create channel of type 'PJSIP' (cause 3 - No 
route to destination)

What settings has mistake? What logic to choose outgoing transport?
