Who are ISP and ITSP?
• ISP stands for “Internet Service Provider” who provides you the internet service. Example: AIRTEL, RELIANCE (Internet Service Providers in India) • ITSP stands for “Internet Telephony Service Provider” who provides you telephony services over the internet. Internet telephony allows you to call any PSTN or GSM line from an IP network Example: ICENET, SATYAM (Internet Telephony Service Providers in India) • If you are looking only for peer-peer calling then you need to get internet connectivity from the ISP. There is no need of services from ITSP. • If you are looking for Internet Telephony then you need to get the internet connectivity from ISP as well you also need to obtain a SIP telephony account from the ITSP.
