VoIP Gateway
VoIP Gateway Voice over IP Gateway is a full-featured server solution allowing to connect ISDN (Q.931, Euro-ISDN) and military digital networks with SIP based VoIP networks. The server combines TEL-KA proprietary E1 / TDM network termitations, with Aterisk (http://asterisk.org/)- recognized open-source thelephony solution. This powerful combination, allows to easly implement and add features that have not been previously available in fixed telephony networks. VoIP Gateway offers following features: •• VoIP calls routing to / from ISDN networksΩ •• VoIP calls routing to / from military networks (STANAG / EUROCOM)Ω •• Support of extended modes up tp 120 channels / 2Mbps Ω •• Support of Eurocom trunk and loop mode Ω •• Support of DeltaMux and DeltaCombiner selected modes Ω •• TDM ports support Eurocom B/C or Stanag4210 physical layer standards Ω •• SIP protocol support Ω •• Codecs G.711 a-law and u-law, CELT, Speex, iLBC, lpc10 codecs support on VoIP sideΩ •• IVR server (including voicemail) Ω •• Conferencing - dynamic and static conference rooms Ω •• Calls interception Ω •• Dynamic / static rating Ω •• And many, many more... Ω Thanks to flexibility of the VoIP Gateway solution, we can implement any feature, service or custom behaviour. Interfaces nad hardware VoIP Gateway hardware is combined of typical 32-bit server (running Linux OS) and any number of TEL-KA USB Endpoints. Each USB Endpoint terminates one or more E1 links (ISDN-PRI or CAS-DTMF) and configurable TDM links (STANAG / EUROCOM trunks/loops). This makes VoIP Gateway solution highly scalable. If you want more fixed telephony trunks, you just add another USB Endpoint. If you have a need to support many VoIP features, than more powerful server can be supplied, or USB endpoints can be distributed among many servers. Additionally, VoIP Gateway can be customized, to allow direct client line connection (ISDN BRI) using V5.2 Access Node. TELKA V5.2 Access Node allows to connect up to 32 ISDN BRA lines, which gives maximum 64 simultanous calls per node.
