Sangoma Vega 400 4 T1/E1 (120 channels) VEGA-VS0111-120
The Sangoma Vega 400 120 Channel VoIP media gateway connects digital telephony equipment to IP networks.
The Sangoma Vega 400 media gateways are supplied with four E1/T1 interfaces which are always fully available regardless of the license which has been purchased.
The unit is purchased pre–licensed to suit the initial requirements of the customer for the quantity of concurrent VoIP calls desired through to 120 VoIP channels. Future expansion is easily achieved in the field & can be provisioned by means of further licenses and expansion modules.
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 & the PSTN simultaneously. This configuration provides:
- No disruption to the configuration of existing equipment
- Flexibility & choice for call routing
Service Provider Applications:
- Customer premises gateway for SIP trunking
- Low-density PSTN gateway
- Survivability for IP phones
Enterprise Applications:
- Enterprise VoIP networking
- PSTN trunking for IP-PBXs
- Enterprise IP telephony gateway
Enhanced Network Proxy (ENP) (Optional)
This option enables continuity of service during WAN/SIP outage and may be configured to operate in a number of ways including:
- Standalone proxy
- IP device survivability
- IP device call routing
- Emergency call routing
- SIP to SIP call routing
Open, Non–Proprietary Interfaces
The Vega 400 gateway supports the following signalling schemes:
- ETSI ISDN
- NI1, NI2, AT&T 5ESS, DMS100
- ISO QSIG Basic Call & QSIG feature transparency
- Channel Associated Signalling (CAS)
All VegaStream gateways can support SIP, H.323 & T.38 FAX.
The Vega 400 gateway has proven interoperability with a wide range of existing telecommunications & VoIP equipment.
