doing GMBH is developing telephony services for customers from many different industry sectors
We are developing telephony applications and services for customers from many different industry sectors (e.g. Health care, Airlines, government,…). Therefore we run our business only on systems we can fully rely and trust.
Our old hardware based telephony router got old. It was used to switch calls between ISDN (TDM) and SIP. This solution was built in a specific chassis with high end cards. This specific chassis with included telephony boards were responsible for the high price of this solution.
Since time is changing and hardware is getting old, we were scanning the market for a new solution. There were several criterias the new system had to match:
- no specific hardware (for SIP)
- ready to virtualize it in the cloud
- possibility to build redundancy
- reliable real time statistics
With the CTRouter we found exactly this. Our new environment is having two hardware chassis which are running CTRouter with Digium cards. We still need Digium cards for some ISDN traffic, but the most is running without it. The two routers offer us full redundancy. Our whole infrastructure is consisting of multiple media processing and application servers, SIP servers, desk and soft phones and gateways. All of them are now nicely interconnected to each other via CTRouter regardless of the fact that they are using different technologies, protocols and even codecs.
The flexibility of the CTRouter will help us as well to reach our next goal – all telephony will be hosted in the cloud as soon as ISDN is not needed any more.
Regarding the costs we are very satisfied about clear and transparent price model. All updates are free of charge.
The team of the CTRouter core development was supporting us during the migration very well. While we provide telephony solutions for our customers we need to have a data feed with enhanced features. This requirement was fulfilled as requested and the customers didn’t noticed our migration.
Old router have had an old fashioned GUI. CTRouter is having a nice structured website which is designed with the latest web standard. As a special feature I would emphasise the real-time routing rules matching and testing.
We are very pleased with CTRouter and with the fact that we have found a reliable partner for hopefully long term cooperation in the future.
