Hi guys,
There are many types of VoIP. Like some VoIP services allow you to call to same VoIP service user or client. And some VoIP service providers allow you to call to all other networks like cell phone networks, landline phone.
VoIP phones are easy to use. You won’t need to do any special cabling. Just connect it to a broadband internet and enjoy phone calls. These phone calls are cost effective as compared to ordinary phones.
