RTP anchoring issue

 

Hi,

 

My SBC connects to two networks; Network-A and Network-B. The design is to have media routed via SBC (i.e, SBC should anchor the media). Currently I can see both ends Network-A and Network-B are sending the RTP to the SBC, but nothing is passed by SBC to either end, resulting a silence (no media). 

 

Both networks are configured on different interfaces of SBC, with different realms. I have enabled the mm-in-realm, mm-in-network, mm-same-ip for both realm, but no success. I played around with restricted-latching but nothing works. 

 

On the SIP trace (detailed one in SBC), I can see the SBC assigning IPs & Ports as per the configured steering pool & looks okay.
