VPN/Voip port related question.

Hi All,

May be my ISP blocked sip port 5060 or they have some voice packet senceing machanism, I used to make voip calls through my linksys ATA (SIP) which, I can't use any longer.

I tried to implement vpn (IPSec) but seems like its also not working.

This device Linksys SIP ATA only working if i dial to (make PPTP connection) vpn server.

my question is, how can I make sure, which port My ISP has blocked and my 2nd Question is: can anyone tell me, IPSec use which ports ?
