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.

Subject: [asterisk-biz] Solutions for ADSL failover and load balancing
We have a customer who would like to offer SIP over multiple xDSL circuits
to their PBX customers. This is both for extra capacity using load
balancing and for failover. The end customers will have a small
Enswitch/Asterisk or other VoIP soft switch at their site, and who wish to
use our customer's service for calls to and from the PSTN.
Failover can be done using RIP or OSPF, but load balancing SIP across
multiple xDSLs is a bit beyond our experience. Has anyone recommendations
of how to do this?
The DSL routers will do NAT, so there will be 2 or more separate external
addresses (so the hosted service needs to know to deliver calls to all).
Forwarding ports on the routers is acceptable, as is some sort of VPN
device.
