Skype has allowed other PBX software to connect to Skype using the standard protocol SIP. This is a good start to opening up Skype’s network to what is used around the world however it still lacks some features which Skype For Asterisk does offer such as calling Skype users.
At the time of writing it costs £4.95 per channel so for 1 incomming and 1 outgoing it will add up to approximately £9.90 + buying the phone number itself for £3.95 per month. This all soon adds up to more than a traditional PSTN landline. Also you need to add Skype credit to the account which are for call time.
For my testing purposes I had only bought one channel for out going calls. I have a landline so people would call that number and the outgoing channel can be used for calls going out to people at a cheaper rate. This means the costs per month is £4.95 + Skype credits.
