Hi All<br>
<br>
I am looking for some insight into FS port numbers. <br>
<br>
The default internal port number is 5060 and when the IP phones
register with FS, one of the phones gets assigned 5060 and the
remaining phones get a random port number assigned (I am using this
command to see the port numbers: "sofia status profile internal
reg"). <br>
<br>
How is this random port number decided on? How can I tie a phone to
a specific port number? <br>
<br>
Thanks<span class="HOEnZb"><font color="#888888"><br>
