Is there any way to change the VOIP dial plan on the BT2700HGV router running software version 5.29.117.6 ?
The default dial plan:
[2-9]XXXXXX|0[12]XXXXXXXX.T|0[12]XXXXXXXXX|0[346]|07XXXXXXXXX.T|08XXXXXX.T|08XXXXXXXXX|
09XXXXXXXXX|09XXXXXXXX.T|00X.T|1XX.T|100|123|1247|142XX|149X|141XXXXXXXXXXX|153|155|1571|
180XX|192|195|*XX*|*XX#|#XX*|#XX#|*#XX*|*#XX#|*XXX*|*XXX#|#XXX*|#XXX#|*#XXX*|*#XXX#|
999|112|1470XXXXXXXXXXX|1471|1474|1475|**[5-9]|**[1-4]X|0500XXXXXX|05XXXXXXXXX|05XXXXXXXXX.T
is fine for the BT VOIP service but if you want to configure the second voice port to use a foreign VOIP service (e.g. a U.S.A one) it doesn't work so well as some numbers cannot be dialled. This makes it very hard to make SIP IP to IP calls to VOIP users in other countries who have a SIP telephone address.
Alternatively is is possible to disable use of the dial plan on one port so that the number sent is exactly as dialled ?
