“That’s a full house because Voiceflex is now fully approved on all Siemens SIP supported systems. HiPath OpenOffice ME is a little different it’s the first telephony application we have seen from a major manufacturer that’s built end to end on SIP standards.
More importantly from a Voiceflex prospective SIP Trunks come included within the main system, free if you like; providing a considerable saving for the end user or more profit for the reseller. There is a cost to install an ISDN 30 card which of course is hardware.”
Taylor says that based on a green field site the total cost to install 30 channels of ISDN including hardware is £3216.00. The total cost to install 30 SIP trunks is £0.00
“The ongoing end user rental costs are £1216.00 per quarter for ISDN30 plus DDI rental charge. SIP Trunks x 30 per quarter are £540 including DDI rental charge representing a saving of 56%. When using SIP Trunks you can also port the customer’s number/s.“
