Re: [SR-Users] Kamailio as SBC and far end nat

There is only one thing left: keep-alive. To keep the NAT pinhole open you need periodic traffic from/to the client. Either enable NAT keep alive on the SIP client, or on Kamailio (nathelper module and save() the contacts just for the purpose of nathelper keep-alive) or on Avaya (e.g. if Avaya

Hello, for dialogs (like subscriptions or invites), you have to use record routing (see rr module) -- so for initial subscribe/invite you have to add record-route header in kamailio, then do loose routing for requests within the dialog (like notify) -- the default config file coming with kama

Hi I'm trying to configure kamailio version 3.3.0 to be a Session Border Controller which only purpose is to handle far-end-nat. On the far end site I have a SIP client with IP '192.168.1.2' which is NAT'ed to IP 'zz.zz.85.230'. The SIP ALG is disabled on the NAT firewall. The SIP client is commu

Hello, if you look to do topology hiding, look at topoh module. If you need a full sbc, it might be better to use dedicated software for it -- e.g., SEMS has an explicit SBC module, other software such as asterisk or freeswitch can do it -- with them you will get specific features such as tra

Hi, I know that kamailio is SIP proxy, but is there any way how to implement kamailio as SBC like OpenSIPS with B2BUA module ? I tried OpenSIPS with this module, but it does not work with mediaproxy module. Mino ___ SIP Express Router (SER) and Kamaili

Thanks - very nice:-) I now have a server installed with Kamailio and rtpproxy. I'm not sure about the routing but I will do some testing on the system. Cheers! Martin On Mon, Feb 20, 2012 at 8:48 AM, Klaus Darilion wrote: > Yes. > > For far-end SIP NAT traversal take a look at the nathelper mo

Re: [SR-Users] Kamailio as SBC

Yes. For far-end SIP NAT traversal take a look at the nathelper module. If you need NAT traversal also for media you need a media relay too - e.g. you can use rtpproxy (Kamailio module + rtpproxy daemon) If you take a look at the default config of Kamailio you see how these modules are used.

[SR-Users] Kamailio as SBC

Hi I'm new to be working with SIP. We have a SIP server and it handles SIP well but it does not handle far-end-nat. Can the Kamailio server be used as a SBC (Session Border Controller) to handle far-end-nat? Just forward all SIP packages to a SIP server and fix the far-end-nat problem? Cheers!

Re: [SR-Users] Kamailio as SBC / LB Media-Servers farm

Seems like the NAT traversal is just broken. just some basic rules: - Call fix_nated_contact only for request from the clients (although it shouldn't hurt if you call it for all requests) - Whenever a message contains a session description call force_rtp_proxy(). Make sure to provide proper fl

Thanks Alex for actually finding the thread for me- I'm reading these thoroughly and let me try these. Klaus, mhome=1 is a good tip let me try it now: The problem is that when I set-up the scenario as I mentioned using Private IPs the end user starts sending the media to the private IP of asterisk

Re: [SR-Users] Kamailio as SBC / LB Media-Servers farm

If you want to have your Asterisks on only private IPs, you will need to use some sort of RTPProxy, the standard config examples typically work for that setup. On the other hand, some people are starting to come back from that topo, and just use Asterisk (or freeswitch) as the RTPProxy. And perhap
