Softphone & Asterisk on same machine in centos?

I am using Asterisk & java application for voip project in centos.
java app use for keep Database with help of mysql & asterisk & monitor everything…
Now i am trying to use open source soft-phone on same machine where asterisk present.
I try pjsua but when ever asterisk on pjsua not work & when ever asterisk stop pjsua works…

Now i am also trying to find out in Asterisk there is App-Konference…is there way to fetch audio coming from 1 sip phone to asterisk & we can send it. like softphone do?

Means person who handle asterisk server he also talk with other sip phones… by headphone which attach to server’s sound card…

or by vbox i can keep running one more centos in same server where soft phone install & in main machine Asterisk, mysql,java etc running…& person can talk with same physical machine to sip phone…

Is this few possibilities i thing…but which one really possible not know?
Any Idea or clue can i get from here?

This is the wrong forum. Please use Asterisk Support in future when asking for support.

As long as you explicitly override the use of port 5060 on at least one of them, Asterisk’s SIP support can co-exist with other SIP user agents on the same network interface. Normally you would override the soft phone.

Thanks david55 for answer my question! I definitely ask question in appropriate forum.
