The Asterisk echo problems were nearly solved today by switching to the Mark3 canceller from the Mark2. During testing this morning we had 1 problem call in 32 calls. This was deemed good enough to attempt to go live again. Then, out of 75 further calls we had 5 problems calls – a couple of which were totally unacceptable.
So, the project has been canned. All VoIP equipment is being returned to the suppliers as unfit for purpose, and the server is being recycled as an upgrade to one of our older servers.
The decision point was reached because we could offer no estimate for a resolution. All the issues are transient problems that are commonly discussed on the internet. Unfortunately, for a production system the failure ratio has to be fractions of a percent, not 5%.
I am very disappointed, but this has been a bit of a money pit. We may revisit VoIP, but not soon!
