Your company’s IPedge phone system can reach as far as AT&T’s IP network.
Toshiba’s IPedge® business communication system has been certified with AT&T IP Flexible Reach SIP Trunking. AT&T offers SIP trunking on its Managed Internet Service (MIS) and virtual private network (VPN) service, which run over AT&T’s global IP network. The IPedge IP server has built-in support for SIP, so you don’t need a gateway device to connect to AT&T’s SIP trunks.
This news might sound like acronym soup, but it’s great news for any organization that has more than one location. SIP (Session Initiation Protocol) is the key that enables VoIP services to work across locations, even worldwide, over a service provider’s managed IP network, such as AT&T’s.
SIP is an industry standard intentionally designed to be flexible and adaptable, but there are many flavors as a result of the standard’s
inherent flexibility. As a result, not every SIP trunking provider interworks seamlessly with every IP PBX. In the haste to get to market early, some IP PBX vendors delivered SIP solutions that had interoperability snafus, requiring lots of troubleshooting and custom configuration — and causing lots of frustration for customers.
Certified interoperability between Toshiba’s IPedge platform and AT&T SIP trunking means you have assured interworking and new options for extending the phone system outside company walls. Consider the possibilities:
- A call to your office number could ring at your desk phone, then your cell phone, then remote office, etc., until it finds you wherever you are, at home or on the road.
- From an airport, a hotel room, a Wi-Fi hot spot or anywhere, you could change these forwarding instructions as you change locations or form temporary project teams.
- You could collaborate with distant colleagues, customers or suppliers using shared Web browsing, desktop collaboration and Web conferencing, all linked to your email and voice mail.
- You could log in to use your personal communications features, message stores, contact lists, preferences, etc. from any desktop or mobile IP phone, which doesn’t even have to be a telephone.
- Your company could publish local telephone numbers (virtual telephone numbers, or VTNs) for the various geographic locations it serves yet handle all those calls in one preferred location.
At the same time, SIP trunking reduces communications cost by extending the value of what you already have. For instance:
- A single IPedge server can support users in multiple sites across town or across the country.
- Calls between locations can run over your existing IP intranet, reducing long-distance costs.
- Converging voice and data on the network reduces infrastructure costs.
- SIP trunks use trunk bandwidth very efficiently, so you can run more traffic on the same T1.
- What’s not to like? Think globally, act locally.
- You can with Toshiba, AT&T and SIP trunking —
- and you know it will work.
