Figure 4 Change Settings for putty
Figure 5 Change Lines of scrollback to 20000
Step 3. Enter asterisk CLI.
Execute command asterisk –vvvvvvvvvvvvvvvvr to enter asterisk CLI.
Figure 6 Enter Asterisk CLI
Step 4. Enable SIP debug.
After entering asterisk CLI, execute command sip set debug ip x.x.x.x to enable SIP debug for a specific IP address. (i.e. sip set debug ip 192.168.6.121)
Note: x.x.x.x is the IP where the SIP packets are sent to or from.
Or you can execute command sip set debug on to capture all the SIP packets which are sent to or from MyPBX. If you are not sure which command to use, please execute sip set debug on.
Figure7 Enable SIP Debug
Step 5. Stop capturing SIP logs when the problem comes.
When the problem happens again, execute sip set debug off to stop capturing the SIP log.
1> If you can’t register an extension, you can try to register the extension again. If you cannot find any SIP packets, it means MyPBX don’t receive any SIP packets. Maybe you should check your network first.
2> If you have any issue of the incoming calls or outbound calls, please try to make a call again, and you will see the SIP packets and logs are printed in putty window. Just copy the content in putty window (follow step 6) and send it to us.
Step 6. Copy All to Clipboard and paste the logs to a document.
