[asterisk-users] Dual Wan Router with Failover

Hi List,
Does anyone know of a good dual wan router that can handle SIP well and can
failover between connections if there is a SIP issue on one of the lines
(meaning there still is a connection however there isnt enough bandwith or sip
packets arent going thru etc.) ?

Thanks.

[asterisk-users] Dual Wan Router with Failover

I've been looking for this as well..  I need to support up to 20 VOIP  
phones over Internet as the Asterisk server is off-site.  We'll have  
multiple cable modems or DSL routers.

I found this device which looks promising - does anyone have any  
experience with this?

Sweet, now that is interesting

anyone have any comments on the load balancing capability of these?

 

 

Cheers,

	Are you looking for load balancing or failover.

	 

	Also is there a cheaper way of implementing load balancing than
$845 appliance?

[asterisk-users] Dual Wan Router with Failover

There are several dual-WAN routers with load balancing and failover,
including the Xincom Twin-WAN series that I have tested OK with SIP (as
NAT): http://www.xincom.com/twinwan.php . Their other products probably
work, too.

	Keep in mind that load balancing on these devices assigns each TCP/IP
*connection* to its own WAN interface. So a large transfer on a single
connection is limited by the bandwidth of whichever interface it's
started on, even if the transfer starts slow enough to get assigned to a
smaller bandwidth interface, then expands to require the bandwidth from
the other WAN. The tech to de/multiplex streams works "well" only when
connecting to a single router endpoint, over relatively few hops that
can lengthen unpredictably the path some deplexed tackets travel. UDP
works better, but it still doesn't really work that well. What works
well is assigning different WANs to different apps' traffic, using
multiple WANs for failover, or just accepting that these techs are
better than nothing, and offer cheap ways to at least avoid a single
point of failure in the WAN scheme.

[asterisk-users] Dual Wan Router with Failover

We've had great results with Astrocom powerlink for load balancing
outbound wan connections.

[asterisk-users] Dual Wan Router with Failover

I have not seen anything yet that does failover based on SIP (i.e. seeing if
there is a lag with sip). Anyone know if that exists ?

  Hi List,
  Does anyone know of a good dual wan router that can handle SIP well and can
failover between connections if there is a SIP issue on one of the lines
(meaning there still is a connection however there isnt enough bandwith or sip
packets arent going thru etc.) ?

  Thanks.
