Configuration

Why I do not see sip packets other then port 5060?

Voipmonitor sniffer by default sniffs packets only on port 5060 from or to. If you need to sniff more SIP ports you need to specify it in configuration. Please see this: Sniffer_configuration#sipport

How to disable timezone check

Go to settings -> System configuration -> Advanced section -> Hide timezone information -> Enable and set to TRUE

Licensing

How to know how many license channels do we need?

Go to GUI -> Tools -> concurrent calls which will show peaks past 14 days. All multiple legs are already aggregated into single channel so you do not need to buy extra channels in case you have two or more CDR per one real call.

How does having multiple sensors affect the licensing? If I add a 2-3 remote sensors to the system, would they use the same license pool?

Central GUI calculates connected channels for the whole database but groups all calls legs as a single call so multiple legs are not counted twice etc.
