Optima Saver uses a couple of techniques to deliver better quality of voice while consuming much lower bandwidth. Optima Saver enabled voice network can handle upto 5 times more VoIP calls than a normal voice network with the same bandwidth.
The basic idea is simple. A simple voice call has a lot of redundant and un-necessary data overhead which are not required for good quality VOIP call. Optima saver performs a careful examination of voice and data packet in the network and strips out anything that is not essential and thus keeps only the necessary packets required to deliver good performance. it also changes the priority of voice packets over all other kinds of data packets in the network to ensure better performance.
RTP Header Compression:
When Voice data is transmitted over the IP network, it carries significant amount of invisible overhead in the header. Some part of those overheads can be stripped without compromising the quality and performance of the call. Also some parts of those overhead data can be compressed without hampering the quality of the voice. Optima Saver implemented this RTP header compression technique in an efficient way so that it can deliver around 5 times more calls in the same network without any compromise in the performance and quality of the calls. In fact, most of the times the quality and performance improve as the required bandwidth is lower than the available bandwidth.
Improved QoS Mechanism for Voice Traffic:
In normal QoS mechanism, voice traffic is treated as normal data traffic. Normally voice traffic and data traffic can co-exit in the IP network. Optima Saver QoS mechanism ensures the delivery of voice traffic with higher priority while data traffic is treated with lower priority. As a result much more voice traffic can be sent as voice traffic will enjoy higher share of bandwidth than normal data traffic. The smart QoS management system makes it all possible with the same bandwidth.
