[asterisk-biz] Solutions for ADSL failover and load balancing

[Linus Surguy]

Is this in the UK or outside? If in the UK there are a number of providers 
(such as www.aaisp.co.uk) which will offer bonded ADSL over multiple links, 
but providing a single IP route, so you don't need to worry about multiple 
IP addresses for SIP servers etc.
