WHAT IS VYSPA SIP?


SIP stands for Session Internet Protocol. For lay people this means that you can make and receive calls through your telephone system just like you would with ISDN lines, except that your calls are routed through the internet.

If the thought of routing your calls over the internet scares you, then you should know that most calls made now in the UK are in actual fact routed across the internet anyway. When you pick up the handset to make a call using your fixed line, it is very likely that the call will be routed to the fixed line provider who will then route it over the internet. The fixed line provider will however charge you a huge premium for the privilege. SIP stands for Session Internet Protocol.
