[OpenSIPS-Users] public ip issue with sip provider

[Matt Hamilton]

Thanks Sammy. Multiple rtpproxies seems like a good solution. I will also look into binding the nics on the opensips server for more bandwidth. 

I thought the design I described below is common. Is it really unnecessary to make all those servers public? I'm sure they will give me an 8 or 16 IP block if I insist/ask for it. 

Regards,
Matt

Hi,
If you want to load balance the rtp traffic then you can setup multiple rtpproxy instances and rtpproxy module would do load balancing of RTPproxies for you,there wont be any bottle neck !

Hi,

I have an Opensips server dispatching to 3 Asterisk servers. I would like to assign public IPs to all of these servers and avoid NAT altogether - phones will also have public IPs. The way I set this in the lab, all the SIP traffic goes thru the SIP proxy (Opensips) and RTP goes directly between the Asterisk servers and the UAs.


The issue is that our provider (they will be both sip trunk and internet access provider for us) wants to assign us only 1 public IP on their voice network - they are saying that the above design is unusual. I'm new to this, is it?


If we end up getting only 1 public IP, I assume putting all behind NAT (or assigning the public IP to opensips and putting the asterisk servers behind NAT) will do it. rtpproxy is also setup on the Opensips server just in case - I can use it to force the RTP traffic thru the sip proxy. Any other way?


All I want to do is load balance the RTP traffic, avoid any unnecessay processing and bottlenecks (rtpproxy, etc.). 

Any thoughts? 

Thanks,
Matt
