| What is SIP? |
 |
SIP stands for Session Initiation Protocol. This is the widely used non-proprietary protocol, or language, which our servers use to communicate with your software or hardware. SIP allows the user to initiate or receive calls using video, audio or simple text messaging.
SIP is not specific to Callcentric and many VoIP providers that actually use SIP allow for inter-connection with your Callcentric account to either place or receive direct calls at no extra cost. |
