I thought the rules of troubleshooting VoIP were:
Rule #1: It's a NAT or ALG problem
Rule #2: Refer to Rule #1

I use Grandstream, and BLF is Broken when trying to use SIP over TCP.
I've never had a NAT problem before. I was just checking the other

I have a couple customers that I let take phone handsets home, the
Grandstream PBX is at our office. It seems that if the SIP traffic
