[OpenSIPS-Users] Proxy question

[Flavio Goncalves]

Hi Travis,

If I understood correctly, you want to balance registrations between
Asterisk PBXs. In the latest versions, Asterisk has support for Path
(RFC3327). By using this on your Asterisk and also on OpenSIPS you can send
the address from where the request was received. Also check if your
firewall does not have ALG (Application Layer Gateway) enabled, it can be
changing your SIP headers, that's why you receive the firewall address
instead of the source address.
