Voipfone allows free peering with some networks on an ad-hoc basis.
Unfortunately this method of dialling is not formally supported and may or may not work depending on the provider's policies.
The format for calling and receiving is
sip:telephonenumber@sip.voipfone.net
like this:
sip:02070435555@sip.voipfone.net
We can't guarantee that any working peering arrangement will stay that way.......
