input SA/realm evaluation

SBC 6350, SCZ9.1

Hello,

I run a specific configuration. There's a parent realm with multiple child realms - as of now I use one child realm only. There're a sip-interface and a steering-pool linked to the parent realm.

There are three SAs sitting in the parent realm grouped in a SAG and I use this SAG for routing.

The SBC pings these SAs using OPTIONS and I receive 200/ok. This is TCP/TLS communication.

This worked fine, but from a very specific reason I needed to set up additional three SAs sitting in the 1st child realm and these 'child' SA pings the same IPs as the parent SAs. I receive 200/OKs. It means that all outbound OPTIONS share the same IP address. All incoming INVITEs share the same IP address - the IP of the sip-int linked to the parent realm.
