TelTel
TelTel, which is based in Santa Clara, California, has launched a program that will allow participating ISPs, ITSPs, CLECs to function as SIP Virtual Network Operator partners. This will enable them to offer their customers SIP-based IP telephony, IM, and other features. TelTel has around 1.3 million users as compared to more than 50 million for Skype. Skype uses a proprietary messaging protocol whereas TelTel uses one that is based on SIP. voipplanet.com reports:
Both offer the same basic feature mix: in addition to the aforementioned instant messaging and presence, free PC-to-PC calls, low-cost call origination and termination to the PSTN. TelTel also offers a modest array of availability notification and 'call me' features in the client interface. Skype offers three-way conferencing and, as an extra-cost option, voicemail.
