Ignore Contact Header
Is there a way to have the SBC ignore the Contact header?
Example:
The SBC (120.10.45.60) sends an INVITE to a PBX which is behind a NAT'd router.
The router's WAN is 80.45.45.60 and PBX is 10.22.19.99.
There is no SBC on the PBX side.
Softswitch -> SBC -> Internet -> NAT'd router -> IP-PBX
When the PBX responds to the SBC's INVITE it sends it's private IP info in the SIP header.
