[asterisk-users] Asterisk not replacing private FROM ip with public IP in INVITE

[TTT]

Something perhaps noteworth, since this is a multihomed system I bound the transport to 172.31.253.4:5060

I don't *think* that would cause Asterisk to use that IP in the FROM...at least it shouldn't.

I tried that (only needed to add rewrite_contact=yes) but it didn't help.

BTW, the CONTACT: line holds the correct ip!  Only the FROM: line holds the wrong (private) IP.

I'm still learning SIP...but I assume the FROM should also hold the rewritten public IP.  Just don't know how to force Asterisk to do that.
