Tks, everyone, working on how to top up the credit.

In some forum, the listen to incoming call is no charge in UK. is it true?
I have 1 voip from hkbn 2b, 1 voip from et263, if i add one voip account, where should i put in in OBI110? or any sample configuration ?
I try to put et263 into voip 3 -5, seems it is not working.
