Manipulate Via Header IP

Hi,

 

I have following configuration in my network

 

[SBC-X] ------> [my SBC] -----> [SBC-Y]

 

SBC-X works over multiple IP addresses - i.e., Invite sent by SBC-X to my-SBC can be from several IP ranges (for example, from 10.0.10.0 / 24 and 150.0.100.0/27 etc).

 

SBC-Y requires to see both Via header (one of SBC-X and one of my_SBC). The Via header of SBC-Y should include a unique IP (example, 10.0.10.0/24 & 150.0.100.0/27 be replaced by 10.0.10.0). 

 

I tried SIP manipulation defining "Any" as match-value and also defining the complete range as "10.0.10.0/24|150.0.100.0/27", but both option fails. I even noticed that my_SBC is checking both Via header, whereas I want it to check only the second Via (Via of SBC-X).
