Availability: Discontinued
Please note that the Vegastream Vega 400 Gateway has been discontinued. We recommend the Sangoma Vegastream Vega 400 as a good alternative.
Vegastream Vega 400 4 x E1 120 Channels
The Vega 400 digital gateway connects digital telephony equipment to IP networks. All Vega 400 gateways have four E1 / T1 interfaces and can be purchased with various VoIP capacities up to 120 VoIP channels.
The Vega 400 has been designed with future expansion in mind and consists of:
- Base Vega 400 unit with expansion slots
- Field-installable expansion modules to provide additional VoIP channel capacity
A Vega 400 unit can therefore be installed with one VoIP channel capacity and then later additional capacity can be provisioned as and when it is needed.
Each E1 / T1 interface can be independently configured as network side or terminal side. The Vega 400 gateway can, therefore, be connected to a PBX and the PSTN simultaneously. This configuration provides:
- No disruption to the configuration of existing equipment
- Flexibility and choice for call routing
Open, Non-Proprietary Interfaces
The Vega 400 gateway supports the following signaling schemes:
- ETSI ISDN
- NI1, NI2, AT&T 5ESS, DMS100
- ISO QSIG Basic Call and QSIG feature transparency
- Channel Associated Signaling (CAS)
All VegaStream gateways can support SIP, H.323 and T.38 fax.
The Vega 400 gateway has proven interoperability with a wide range of existing telecommunications and VoIP equipment.
