So it does seem to support it. Sebastian -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] load balance with 2 wan connections
Hi, One possibility that you might want to explore is OpenVPN. If your VoIP clients support OpenVPN (either through a local Openvpn client on the clients network being used as an OpenVPN gateway, or through individual clients supporting OpenVPN (laptops with softphones, or I've heard of one particular hardphone supporting OpenVPN - but can't remember which). Once you are using OpenVPN - it is a bit easier to setup a failover scenario - or even load-balancing - as Openvpn has some inbuit functionality in this direction. There has been some recent discussion on the OpenVPN list about load balancing and failover setups if I remember correctly.

Re: [asterisk-users] load balance with 2 wan connections
We have another gateway in the USA that will send traffic to both IPs. The US gateway will load balance the traffic to both IPs. This is not used for phones. It is used mainly for wholesale traffic. Asterisk is being used as an SS7 gateway. Each DSL limits us to about 16 calls. We are thinking of combining DSL + DSL + Cable ISP on the same box and have our USA box send traffic to all 3 IPS.

Re: [asterisk-users] load balance with 2 wan connections
some providers do serve inbound by sending the traffic to exact IP, some do accept the registers from any IP. in second case for Inbound failover, you might just to "register => " using another interface/IP address. here a new question arose: how to "sip-ping" some phone number to see if it's alive?

WAN: 1 DSL + 1 Cable ISP. I seem to have missed the start of this - however I'd suggest getting hardware to do it for you - e.g. Draytek 2820 - will work out of the box for you as it has both an ADSL port and an Ethernet port for the cable presenstation. Is this WAN connection used to reach an ITSP or to reach phones ? A good point - if to reach the ITSP then it'll be fine if to reach phones then your effective external IP address will alternate between the 2 - so the phones won't always be able to connect - but you could start to fiddle with dynamic DNS solutions, etc. Not perfect though.

Second SIP is hard enough to NAT and route with a single IP let alone 2 or more and probably dynamic! Third, load balancing/fail-over is not a simple matter even doing by hand with Linux or BSD, there will still be issues with static routing and such. There are some cheap hw that may claim it does, but most probably it will not be meant for VoIP, SIP or IAX.
