Advantages and disadvantages of the H323 technology

The H.323 technology has advantages and disadvantages.

The advantages:

1. Managing Bandwidth: H.323 allows good management bandwidth setting limits in audio / video stream to ensure the proper functioning of critical applications on the LAN. Each H.323 terminal may proceed with the adjustment bandwidth and changing the flow based on network behavior real time (latency, packet loss and jitter). 
2. Support Multipoint: H.323 allows for multipoint conferencing via a structure centralized MCU (Multipoint Control Unit) or ad-hoc mode. 
3. Multicast support: H.323 also allows to make multicast transmissions.  Interoperability: H.323 allows users to not worry about how which is communication, the parameters (codecs, flow ...) are traded transparently. 
4. Flexibility: an H.323 conference can include heterogeneous terminals (Studio videoconferencing, PCs, phones ...) who can share as appropriate, to the voice of video and even data with T.120 specifications. 

The disadvantages of H.323 technology are:

1. The implementation complexity of the architecture and problems as regards the convergence of telephony and Internet services and a lack of modularity and flexibility. 
2. Includes many options that can be implemented in different ways by the manufacturers and therefore pose interoperability problems.
