The simplest and most relevant I should say. Just to add to that, first port is TCP port and the other two are UDP ports assuming you are using SIP protocol.
This is the only answer that didn't require the original poster to have to know/learn anything, and thus while it is the 'best' answer, it also doesn't lead to any increased understanding on his part.
SIP is most commonly transported over UDP, not TCP. -- Kevin P.
