SIP Gateway

Need the flexibility of Voice over IP communication
without an expensive upgrade to you current phone system? 
ANI will design a solution to meet your specific requirements.

How can a SIP Gateway help?

  • Use the internet to have a business phone at a home office.
  • Use SIP Trunking to reduce expense, especially with International calls.
  • Use SIP Tie-Lines to provide FREE calls between company locations.
  • Use SIP Trunking as a backup to regular Telephone Co. circuits.
  • Use SIP Trunking to provide additional capacity for your legacy phone system.
  • Use SoftPhones on laptop computers for a low cost telephone alternative when traveling.
  • Use your imagination, and together we will find many more ways to add capabilities to your non-IP phone system while reducing your overall cost!

What is SIP?
SIP, or Session Initiation Protocol, defines a method for establishing a communication session.  In the telephone world, it provides a simple way to set up and disconnect phone calls over a data network such as the Internet or a private Enterprise network.  It is very similar to the protocols that make the World Wide Web possible, but instead of allowing a person to interact with web pages, it allows people to talk to each other.  The greatest advantage of SIP is that it is widely accepted and available, just like the World Wide Web.

What can SIP do for a business?
SIP will provide a business with two advantages:
Primarily, SIP removes the need for the direct physical connections that are required in legacy telephone systems.  In the traditional telephone network, if you want a phone connected to a phone system, you needed to connect it directly to that phone system.  With SIP, the phone can be anywhere in the world, as long as both the phone and the system have access to the same data network.  The same is true for connections to the telephone network; where a direct physical connection was required in the legacy phone network, with VoIP, a phone system can connect to any telephone network, anywhere!  
Second, SIP provides a simple way to tie computer applications to telephone calls and to communicate more information about the calls.  Through SIP, computer applications can easily interact with the calls and the callers, to ask for more information, to look up information, to route calls based on any criteria, or originate calls based on any criteria.  In Summary, SIP and SIP related applications developed by ANI and others, allow a business to control it's phone calls to meet just about any requirement.

Is there a down-side to using SIP?
Connecting a phone over a data network is certainly more complex than connecting it over a pair of wires.  When the data network is the public Internet, much of that complexity is not under your control.  When the data network is a corporate network, there is a lot that can be done to protect the phone calls, but it comes with some expense.  If needed (and if practical!) data networks can be "tuned" to support SIP calls, but the expense needs to be balanced against the business requirements.  SIP can be made to work in most cases, reducing cost and increasing flexibility, and ANI can help you make it work!
