SIP Client For IP-Phones [Case Study]

DSP Group Case Study – The worst nightmare when starting a new project is not having clear requirements. IP-Phone vendors need to define what will be the modular architecture for the voice application, considering the SIP Stack, Media Engine, Call Manager, interaction with the User Interface, and certainly the provisioning and troubleshooting method.To address this complex situation, IP-Phone vendors have an important decision to make:Which SIP Client for IP-Phones should be integrated to ensure mobility, security, easy management, but most importantly, faster return of investment while bringing customer experience to a higher level?M5 Technologies collaborates with IP-Phone vendors by providing the M5T SIP Client Engine (SCE), enabling the most reliable and secure SIP implementation of a wide variety of telephony components for any generic or tailored SIP implementation.M5 Technologies has built a long term and reliable partnership with important partners such as the DSP Group, who has implemented the M5T SIP Client Engine (SCE) with the DSP Group’s DVF99 SoC family, bringing M5 Technologies SIP expertise to IP-Phone vendors developing first-class products for business communications.
