We require an expert level developer-engineer with technical ability & high level of knowledge in the development of VoIP/SIP hosted telecoms platforms IP-PBX such as FreeSwitch or other (Asterisk, etc). We are creating a Call Tracking platform with our backend connecting into Simwood. Rather than API to them, then create a script from their CDR to quirey on our local mysql DB, we have been advised to opt for creating a VoIP Switch and utilise SIP to connect to our wholesale provider. Our intention after the Call Tracking solution was always to later add Outbound (ie; SIP trunks & hosted IP-PBX) Seats and mobile offerings, etc, enabling us to create a 1-Stop Comms portal for our customers with Simwood behind this. If you have the high level knowledge and experience in the developing of Hosted IP-PBX platforms, Call Tracking platforms, FreeSwitch or other, please get on touch
