Good luck with that.
The BT 'Home Hub' and 'Business Hub' routers they supply with retail
ADSL and FTTC products seem to have a very poorly written SIP ALG in
them that cannot be disabled [0] easily. This seems to play havoc with
any attempt to hook up SIP devices - even just one handset.
[0] I have read that it's possible to disable the ALG through a telnet
session to the router, but it's somewhat fiddly and doesn't always
'stick' - so has to be repeated whenever the router is restarted. In my
experience it's far easier just to replace the router with something
competent.
Kind regards,
Chris
