Challenges:
More and more carriers today are seeking to replace first line voice telephone services – usually PSTN landline services - with VoIP telephony services. The Basis MCCS (Multi-Client Communication Suite) technology answers that need.

New services must be transparent to the subscriber, assuming traditional landline numbers are maintained, and available on a cost-effective carrier IP network. In order to face the challenges in this market, carriers have several key requirements:

• Cost-effective, short time to market with clear evolution strategy
• Interfaces must be maintained to existing class 4/5 switches in the network
• Interfaces must be maintained to existing subscriber back-office ticketing system
• Geographic redundancy of the solutions network elements is critical

Introducing First Line Voice via VoIP means a future-proof, scalable and flexible replacement of the legacy voice network to further reduce the cost structure. At the same time, building an IMS core provides the opportunity to develop new services that the carrier wants to offer to business and consumer subscribers over an all-IP network.
