A dynamic resource allocation strategy for VoIP systems based on SIP

In order to explore the feasibility and real-world application advantages of dynamic resource allocation in VoIP (Voice over Internet Protocol) networks using SIP (Session Initiation Protocol), this paper proposes a SIP-based approach to improve voice quality levels and optimize VoIP resource utilization. The method adopts HMM (Hidden Markov Model) to model the dynamic changes of SIP communication traffic and combines with the characteristics of SIP protocol to realize the dynamic adjustment of voice traffic resources within VoIP. The final realization provides good communication quality and network service QoS (Quality of Service) received by end-users through effective prediction and resource adjustment of SIP communication traffic and server load in VoIP communication, which has a constructive impact on improving the level of voice quality received by end-users.
