[OpenSIPS-Users] issues with sharing media-relay between multiple opensips proxies

I don't think there is anything wrong with what you are trying to do.  You
should only call engage_media_proxy once though.

Look at what Dan Pascu says in his reply.
"*2. by calling use_media_proxy twice, the 2nd call won't overwrite the
previous value. Unfortunately, this is not a mediaproxy issue, is a generic
opensips issue that results from the way changes are applied to the existing
message using lumps. Any other opensips function that modifies the message,
if called twice will corrupt the message by appending each change after each
other, instead of overwriting the previous one. So in case of mediaproxy you
will see 2 IP addresses concatenated like: xx.xx.xx.xxyy.yy.yy.yy where the
IP address was replaced.* "

So you need to figure out how to only engage_media_proxy once if you are
going to use two OpenSIPS servers.

Hope that helps.
