    Make sure your backup ADSL supports fail over of the external IP that you use to talk to the SIP trunk as well though.

    well the BRI could handel that , but we do have an analoug phone in reception on a PSTN in case the system goes down.

    Our last failure was a remote failure on the ISDN30 at the main site, I routed outgoing calls over the ISDN2 at the second site (1Gb Wan link) altough that was only 4 channels so people were told EMERGANCY ONLY! And the DDI's did not work for incomming.. Foolish thing is we are with a 3rd party call plan company so BT don't want to get involved, and 3rd Party don't open till 9AM!

    BT support is staggeringly one of the better ones!
