Actually, we have been struggling with intermittent loss of registration
issues with all our voip.ms accounts. We have tried different POP's,
all kinds of different registration settings. We have sent them packet
captures showing the problem but still no progress.
Just yesterday we figured out, you don't have to use registration if you
have a static IP. Everyone says you cannot use IP auth with voip.ms
because they cannot send inbound calls via port 5080. The answer is to
setup you DID's to use SIP URI for inbound and use IP auth for
outbound. Your SIP URI would look like {DID}@pbx1.example.com:5080.
If you don't add the 5080 port then you will not be able to transfer the
call.
