Which VoIP Service is Right for You? VoIP Problems Discussed

By Joe Robertson

There are a few problems associated with VOIP. Like, if the broadband connection is problematic, if there is a conversation that is taking place between two VOIP users and a few IP packets get destroyed or there is a delay in its reaching the destination at any point there is a pause for a few moments, rather no voice is heard.

This happens more in networks that are saturated or when the distances of the call are long. The voice quality has improved a lot today though and it will get better with time.

It is considered better to use the media that is 'packeted' in terms of VOIP as these works on multi-path routing or the incoming and outgoing packets take different routes. This reduces the effect of the minute failures.

There are a number of protocols that help in supporting the report of QoS/QoE which are for VOIP calls. Like RTCP XR (RFC3611) or the SIP RTCP Summary Reports, H.248.30 and MGCP extensions. The RFC3611 VOIP metric report support the feedback which is related to the QoS problems.

It is a little difficult to send faxes through VOIP. The voice codec that already exist are not meant to be sending faxes. Everyday technology is changing, everyday a solution is thought of for fixing this problem. Efforts are being made to answer this problem by defining a solution based on a different IP for sending Fax. These include the T.38 protocol.

Other solutions have also been thought of. Treating the system of fax like a system for message switching and it doesn't need a great data transmission, like sending over a fax like an attachment with the email. The system at the end can buffer the fax data that is incoming prior to its display or its being printed.
