VoIP The Future Today
Make the switch
We recommend business move from the legacy ISDN system to Voice over IP without delay, since the feature set of VoIP systems leave legacy techlology floundering and the capital cost reductions in hardware, often zero, maintenance, also zero and call costs, yes also zero, will surprise you. Voice over IP, the future today…
Here are the top 4 benefits of SIP over ISDN:
Number portability and flexibility
There is not geographical location requirements for numbers and SIP permits out-of-area numbers to be used since your phone number is attached to an IP address instead of a physical telephone line. So, for instance a New York number may point to an office in London. Additionally, ISDN takes 6-8 weeks to implement, whereas SIP takes 24 hours to spin up and spin down.
The bottom line is important for every business and with SIP savings are substantial. With ISDN your voice and data are on different lines, whereas with SIP you can reduce costs by having them on the same one. Also, SIP trunks can greatly reduce call charges including international calls and free calls between multiple sites and offices on the same network.
You can calculate the cost savings of adopting SIP with Gamma’s SIP vs. ISDN cost calculator and see for yourself.
SIP is deployed across your business’s existing WAN which means that you can add additional trunks in high demand and subtract them in low demand respectively in order to easily scale your telephony needs according to your business needs.
Incidents happen and at some point your service could be interrupted by a network failure, a hardware problem, natural disaster or just bad weather. Luckily, one of the biggest benefits of SIP Trunks is the better reliability and much simpler disaster recovery when compared to legacy phone systems. If your business needs a zero downtime environment, SIP trunks allow automatic failover solutions to be implemented so that your numbers will divert to other locations without loss in service.

Amazing company to work with, they have all been so proactive and helpful, nothing has been too much trouble and we are so pleased with our new phone system. It also came in at a saving for the charity compared to our previous supplier. I couldn’t recommend the Pink team highly enough.
