Cloud Asterisk server


I have installed the Asterisk 1.8.x version in my cloud centos 6.5 linuux instance.

My trouble is, sometimes my sip soft phones has disconnected automatically with this Cloud Asterisk server… i have no idea where i have to check.

But restarted the this asterisk service in that Could Asterisk instance, all my SIP soft phone is getting up (registered). I’m thinking, this is not permanent solution for this.

Please assist me to fix this problem as permanently, what & where problem was happened?


Your phones may be losing their NAT path to the server. In your sip.conf, set qualify to 60. This will cause Asterisk to send test packets to your phones once a minute, to keep the NAT routing between them alive. This is just one of the possible problems, though.
