X-Call Session Control Function (X-CSCF)

Build a core control layer in your IMS network that supports interoperability and access-independent end-to-end service. Tekelec’s CSCF product creates a core session layer that gives you the flexibility to reuse common components like presence and location servers and interwork technologies to deliver converged services across any access network. And, because Tekelec’s CSCF product is built to 3GPP standards, you can avoid the pitfall of creating IMS islands of vertical applications that result from deploying non-standard, proprietary IMS or SIP solutions.

• Deliver advanced, multimedia applications
• Migrate to IMS at your own pace without a major network overhaul
• Deliver IMS services without interrupting revenue from your existing services
