Disable SIP A.l.G. on Plusnet free fibre optic router

[#1]

Dear All,
I am looking to upgrade my phone system to VOIP, and the supplier has asked if the router, that is supplied free of charge from Plusnet, can have the SIP ALG disabled.
Many thanks
Danny

Which router do you have ?

[#3]

The Bt hub 5

There doesn't look to be a way to disable sip alg in the HH5, but there's no evidence whether it does have a sip alg.

The above site suggests that voip will work with the hh5.

i've had no issues running a voip phone with a HubOne.

I seem to recall there was someone recently who was having problems with the PN router with multiple voip accounts on Gigaset baee unit. Although that was a hub zero, the problem was supposedly down to being unable to disable the SIP alg http://community.plus.net/forum/index.php/topic,148321.32.html
