Hi Guys. Sorry If you guys find this very basic. I have tried google it and read lots of forum but still don't undrestand. This what my question is.
I have A to Z termination with one company. any I pay per min for local or international call. someone told me get sip trunk you will save mony. why do I need sip trunk if I already have termination. If I get sip trunk how would I save money. can someone explain to me.
