[OpenSIPS-Users] Mediaproxy wrong port, bug?

[Jerzy Ptak]

Hi,

I have spent some time trying to debug this issue.
Despite the fact that depending on the individual case you can find 
workarounds, this is a mediaproxy issue. The problem is caused by the 
way mediproxy is processing media packets and setting up forwarding rules.

Before the forwarding rules are set up, mediaproxy waits and passes on 
media packets between both sides of the session. When mediaproxy 
receives at least on media packet from each side then it is setting up 
forwarding rules. It seems to be that, because the forwarding rules 
setup is not atomic there is a time window in which media packet that 
have been handled by mediaproxy will be sent out by the system (kernel) 
from the incorrect port.

I have created a fix for this issue, which I am allowed to contribute 
back to mediaproxy. Can somebody from mediaproxy team let me know where 
can I submit the fix.
