WHy not installing rtpproxy and proxying all
Because I would like to record some calls and I dont know RTPProxy's features, maybe it could record ?

WHy not installing rtpproxy and proxying all rtp to the inside uase kamailio to load balance them, it will be transparent on the inside perhaps a cleaner solution?

As I recall it is sequential, but not from the start everytime, it is incrementing all the time.
If You are running three servers, then with a 100% identical load, one would expect an average of 2 failing attempts per call.
The reality I see is however often very different RTP ports, most likely because load isn't 100% identical.

Well, indeed, but a sequential scan of many consecutive ports like this from the bottom of the same range can be quite a latent operation. So at the very least the allocation strategy would benefit from being random. Does Asterisk take that approach?

No there is no such thing as magic.
The most obvious way to implement the RTP port handling, is to first open the next UDP port in the OS, and then report that back in the Invite/200Ok. If the port cannot be opened, then simply try the next in
line.

Maybe there is an magic device? I know that if we have an asterisk, that become to us with default configuration of rtp ports sets to 10000_20000. And each call choose the one port fron that range. So if we have several asterisks with default configuratiin of rtp, there is possibilities to have 2 concurent calls each through another asterisk instance with this same rtp port. Am i right?
So mqybe this magic device could see source IP address and route rtp to correct adterisk?

You may not have enough calls for RTP port collisions to becomean
issue. Otherwise, I'm not sure how you're avoiding it, sinceAsterisk
isn't aware of which ports from within the range are in use. -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 <tel:%2B1-706-510-6800> / +1-800-250-5920 <tel:%2B1-800-250-5920> (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-usersmailing
