Flexibility throughout the IP migration

All C3 products are TDM and SIP supporting so they can be deployed at any point in the IP migration (we have a number of hybrid reference sites). This allows our clients to extend the life of existing infrastructure with leading edge applications that can simply be migrated across to SIP, as and when required.

We pride ourselves on the long term relationships we have with our clients who choose to work with us because, as a niche technology specialist, we offer highly advanced applications, expert technical support and flexible commercial terms.
