Couple of bits of advice needed please. First I cannot figure how to call a contact using sipgate instead of the mobile network, if I go to dialpad I can choose call type but it is unclear to me how I choose sipgate instead of cellular for an existing contact.

Secondly I am trying to call home on sipgate by dialing the same voip number logged on my phone. I can be heard but I cannot hear home on my 900. Any ideas please?
