Westcom is the leading UK partner for IP Cortex and has been for 10 years.  Despite telephony being a very crowded market, we have chosen to work with IP Cortex because customers who use the product continue to tell us that it provides all the features they require and offers excellent value.

IP Cortex don’t licence their on premise phone systems by user, meaning that as a business grows adding more extensions costs nothing more than that of the handset itself.

If you’re looking for a phone system which provides early return on investment, rock solid reliability and a full feature set which doesn’t see you needing to buy a load of expensive licences, then IP Cortex is the ideal solution.  Contact Westcom Networks for more information and pricing.

Award winning commercial legal firm selects high availability ipcortex VoIP solution to deliver flexibility, functionality and resilience

The challenge

Shulmans previous phone system supported a mix of analogue, digital and IP lines, and was not even using basic facilities like voicemail and caller display.

The system also had numerous different handsets and was extremely unreliable, as IT Manager Ross MacIntyre explains:

Every two or three weeks we’d have an issue that needed fixing, so it was a real pain. We were using a third party supplier for support, but even though we paid a maintenance fee they were always trying to sell us extra things to fix issues! Having all the different lines and handsets was also a concern, as every time someone moved we had to physically re-patch a phone in, so it was a bit of a nightmare. It was obvious that we needed to change as the functionality was severely lacking, and I knew from previous experience and from research that there was so much more we could get out of a new phone system.

What we did

A full RFP process was carried out, but Ross also spoke to contacts at Westcom Networks, which supplies Shulmans’ firewall solution, who suggested that he consider including ipcortex in the process.

The new solution has 115 extensions and uses Polycom IP450 handsets with HD Voice. Most notably, it actually uses two VoIPCortex Pro IP PBXs which are set up in a high availability configuration.
Ross and the team started setting up the new handsets the week before the switch-over, as well as holding awareness sessions in the boardroom.

People were using old system until 6pm on the Friday, then we swapped everything over at the weekend and when people came in on the Monday they were on the new system. It was great, it just worked and was completely seamless. The user base saw the leap forward we’ve made with all the new functionality and they were suitably impressed – there was certainly appetite for it within the business.
