There was a requirement to provide voice and data communications on Songo Songo Island.for an on-shore drilling campaign.
As there were no land line facilities available VOIP was the only solution.
MACOM Consulting, the data network suppliers installed a C Band VSAT on the island with a 512K synchronous connection.

SGJ Solutions Installed a Vegastream ISDN2 unit in MACOM's London office as the client did not have a UK presence
A Snom 4S Proxy was installed to drive the VOIP system, with Snom 300 handsets deployed on the island.
VPN tunnels were then built between MACOM offices,Songo Songo Island and clients main office in Dar es Salaam
The Panasonic phone system installed at the Dar office was then connected to UK Vegastream via a Linksys ATA, thus providing VoIP capabilities on the switch.

• The Island could communicate with the Dar office despite a double hop VPN with a 1200ms to 1400ms latency and vice versa all for no cost

• The Island could dial normal PSTN numbers by breaking out through London

• Selected handsets on the Island had the ability to be dialled direct via London DDI numbers

• The ability to hold conference calls between sites was also possible

• The system has created considerable cost savings

• This model is now being looked at by several interested parties in the geographic location
