afaicr, snom supports vpn.
Though probaby just plain setup, no special configs like load
balancing/H.A.

Hi,

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.


Just a thought,

Sebastian

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.

The biggest issue with any solution to use two different providers for
your IP service that will be used by your VOIP provider to deliver
calls to your Asterisk server, is that each internet service will have
a separate address. Therefore, for INBOUND calls, your VOIP provider
will have to do the load balancing. For outbound calls, it won't be
that hard as long as your provider allows you to send calls from both
IP addresses.

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?

Re: [asterisk-users] load balance with 2 wan connections

2010-12-27 Thread dave george
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.

Dave

 Need some advise or paid help on running asterisk on two WAN connection.  I
 need load balancing and failover support.

 WAN: 1 DSL + 1 Cable ISP.


Is this WAN connection used to reach an ITSP or to reach phones ?
