Voyager Modem

Im just switching from BT to Post Office homephone.
Though the post office is going to supply a wireless router Im interested to know if the Voyager could be modified at all to use the PO or for that matter any other service ??

depends on the model and perhaps the firmware. There's a Voyager hacks site somewhere around that may help.

If it's not locked to BT it'll work on the PO but you'll need to extract the login details from the supplied kit.
