VoIP Services

With an emphasis on open standard SIP based services. A wide range of services are on offer and we don't intend to list them all. However, we would like to achieve a representative cross section of the voice over IP market. Some services provide only a sip server ( directory and setup services ) where the bandwidth required for the call is provided by the broadband service of the individual or business. Most of these services are available to anybody anywhere in the world. Some services include dedicated broadband pathways and voice gateways into the global PSTN network. Most of these are marketed as alternate long distance carriers and/or reginal carriers. Incumbent Telco's are moving to IP voice for long distance and expect to deliver voice over broadband to business then residential customers. Many such offerings are limited in their geographic scope to local markets. We are also seeing an increasing use of VoIP through wireless broadband connections. This trend will likely continue as mobility operators see VoIP as an opportunity to shift from a single residential line to multiple mobile phones tunneled through a voip based micro cell. This is a possible market control strategy. Free peer-to-peer calling within the domain of a single service provider is commonly viewed as a marketing ploy. If you can make free calls then you will get your friends to sign up. However it flys in the face of the universality of our current PSTN networks, replacing geographically local calling with corporate locality. Not a good trade off. Free SIP calling between services is expanding to include peering with large exchanges like Universities. With a little imagination it becomes clear that the service that provides the best free peering will become increasingly attractive to the customer.

Number Translation

The word "ENUM" refers to the IETF protocol that takes a complete, international telephone number and resolves it to a series of URLs using a Domain Name System (DNS)-based architecture.

" is a non-profit ENUM registry for Telephone Number use on the Internet and Internet type networks. Our mission is to provide a sustainable, verified registry of telephone numbers for dialing on the Internet using Voice over IP, Email, Instant Messaging and other communication protocols. "

Google Talk free beta:
"Service choice is something you have with email and, for the most part, with your regular phone service today. This means that regardless of whom you choose as your email service provider (Gmail, Hotmail, Yahoo! Mail, your school or ISP, etc), you can email anyone who is using another service provider. The same applies to phone service. You can call someone even if they do not use the same phone company as you do. This allows you to choose your service provider based on other more important factors, such as features, quality of service, and price, while still being able to talk to anyone you want. … Unfortunately, the same is not true with most popular IM and VOIP networks today. If the people you want to talk to are all on different IM/VOIP services, you need to sign up for an account on each service and connect to each service to talk to them. … We plan to partner with other willing service providers to enable federation of our services. This means that a user on one service can communicate with users on another service without needing to sign up for, or sign in with, each service. … Google Talk supports XMPP with the beta release. We plan to support SIP in a future release. Additionally, we will evaluate other protocols as appropriate, to continue to deliver on our commitment to open communications. … Google Talk supports a custom XMPP-based signaling protocol and peer-to-peer communication mechanism. We will fully document this protocol. In the near future, we plan to support SIP signaling. … Today, Google Talk supports the following standard voice codecs: PCMA, PCMU, G.723, iLBC. We are also evaluating the Speex codec. We also support codecs from Global IP Sound: ISAC, IPCMWB, EG711U, EG711A … While the Google Talk client is only available on Windows today We look forward toGoogle Talk client supporting Linux and Mac OSX in the future"
