[Asterisk-Users] Trunk Groups and Multiple Asterisk Machines

[Sean Cheesman]

I've looked over the howto, and have the TDMoE "span" up.  I am going to do
some testing.  Ideally, I would like to be able to span 3 or 4 asterisk
boxes for high density purposes on their own network (dedicated TDMoE
network).  That seems like the easy part!  If anyone can give me any
feedback or tips on the best way to configure the TDMoE links within
Asterisk, I'd really appreciate it!  Like you said, it seems to be used very
little!  Thanks!

Sean

You should be able to do this with TDMoE (TDM over Ethernet) which is 
a little-used feature of the Zap drivers.  There are two ways of 
doing this: individual trunk groups in a cascading failover 
situation, which is a well-known configuration with TDMoE (see below 
for howto) and then perhaps a more interesting way that creates one 
huge trunk group spanning multiple hosts, which is not documented in 
the howto but I can't think of why it wouldn't work.

I have not actually tried this, but in theory it should work as long 
as your servers are all on the same ethernet.

See Wasim's mini How-to on http://www.convergence.com.pk/TDMoE-HOWTO 
and then think about it for a while and modify it so that the group 
spans multiple hosts.  Let us know how it goes; I think this might 
actually be a pretty interesting experiment if it functions as 
expected.
