Of course telnet uses TCP packets whereas your PAP2 is probably set to use UDP packets for SIP messages. Did any of your test programs use UDP packets?

Have you used Wireshark to monitor packets to and from your PAP2?

How do you know that your ISP has not switched from simple blocking of port 5060 to a more sophisticated deep packet inspection?
