We have installed FreePBX on a virtual server, under VMware
The system is in trial mode, with around 30 extensions and 1
trunk, and is performing well, with one significant exception that is delaying
our roll-out to the users
When installed on a server with other virtuals running,
voicemail prompts are slurred, i.e. when playing back, the voice pauses, then
starts again, then pauses etc. This occurs
randomly on most (but not all) calls, but on some at least every 2 – 3 minutes.
If we move the virtual to our test server, and run it
without any other virtuals on that hardware, the problem disappears.
We suspect the system is being interrupted by disk activity
(or something else) from other virtuals on the server, but have not been able
to confirm this, or find a setting that fixes it.
The FreePBX virtual setup includes 8,800MHz CPU reserved,
8,192G Memory reserved, Hard disk share set at High (share value 2000, all others
at 1,000). It has 4 CPU allocated, and Thick Disk Provisioning of 1,000G. We therefore don’t believe the application is
being constrained by the available resources in the normally understood manner.
We have not installed VMware tools on the virtual, to avoid
any timing issues from that.
The FreePBX is a new install using the 64Bit FreePBX 2.11 Linux
6.5 downloaded ISO.
When browsing these and the Asterisk forums there is much
conflicting information whether this should be run in a virtualised
environment, but recent posts seem to indicate many are doing this now. We believe having to downgrade to a
stand-alone server would be a significantly backward step for system support
(all our company servers are now virtualised), so would like to explore all
available options first – but have run out of ideas ourselves.
Can anyone advise us?
I am happy to post config files, if someone points me to which ones would
