We can trace specific calls according to their caller numbers or called numbers. In miniSIPServer main window, please click menu "maintian - trace on caller/called number".
It depends on what scenarios the calls are. If a SIP phone cannot register itself to miniSIPServer, it is better to trace its messages accroding to "caller number". If calls to a target number are often fail, it is better to trace them according to the called number.
The traced number, no matter caller number or called number, can be a number prefix. For an example, if you set the traced caller number to be a prefix "1", calls from sip phones "100","101" and so on, will be traced at the same time. If the number is set to be "100", then only "100" calls can be traced, "101" and others will not be traced.
Sometimes we cannot know exact numbers in some scenarios. It often happens when miniSIPServer is working with a SIP server or VoIP gateway. Then we can try to trace its calls according to its IP address.
In miniSIPServer main window, please click menu "maintain - trace on IP address".
The target IP address can be a complete IPv4 address or IPv6 address.
In another way, it can also be the prefix of a IP address. For example, if the target IP address is set to "192.168.3", SIP messages, from address "192.168.3.1", "192.168.3.2" and so on, will all be traced together.
