Is there a Cisco solution to relay/translate between RTP sessions? I will have an application which will handle the signalling itself between VoIP end devices but would like to use a professional equipment to connect the medaia streams transported in RTP.
Thanks,

Not completely clear on the exact application and the network setup. But have a look at IP-to-IP Gateway, which supports the RTP Flow through mode (besides flow around mode), but IP-to-IP Gateway will be involved in the signaling as well:

Another thing you may look into (depending upon your application) is inserting a Firewall in the middle: PIX will modify the RTP/RTCP port numbers in case you use PAT/NAT and VoIP Signaling will be inspected by PIX and modified in case of NAT/PAT.

Thanks for the reply. This IP-to-IP gateway is something similar what I need, but as I see it cannot be used without signalling.
I am not able to open this link with my CCO account. Can you send the doc in email to gkracher@euronetworldwide.com.
Many thanks again,

Try the below URL:

You'll find IP-to-IP Gateway Datasheet, Q & A etc and it should work without any need of a CCO userid. If it still doesn't work, then I can email you the docs.
