Can FreePBX, or AsteriskNOW be installed ontop of Linux RedHat (CentOS6). I am moving to the cloud (using SOFTLAYER ibm). Right now, we are using FreePBX with soundpoint 550 and 335 phones.

I Have installed Asterisk from scratch as well FreePBX also on the cloud, It works really well. I have used Amazon AWS, Digital Ocean, Solar VPS

AsteriskNOW cannot be installed on anything other than a bare machine.

It is normal to install Asterisk on Linux, as CentOS is Linux.

Using a virtual machine for a realtime application is not generally advisable. For VoIP it may result in excessive jitter or choppy audio from voice announcements.

This guidance for Lync should apply to any SIP PABX: … 99035.aspx although it will assume a machine on the local LAN, so networking issues are under control. I don’t think normal cloud servers have the level of control needed to comply with those guidelines.

Thanks for the feedback amblorixg12 and david55 :smiley: :smiley:

After typing in asterisk -r, I receive a message like the one below.
Connected to Asterisk 13.2.0 currently running on justhost (pid=3005)
Disconnected from asterisk server
Asterisk cleanly ending (0)
Executing last minute cleanups
Why did this happen, and how can i fix it?

root@justhost [~]# asterisk -rx "logger reload"
Unable to connect to remote asterisk (does /var/run/asterisk/asterisk.ctl exist?)

root@justhost [~]# asterisk -vvvvvvc
Asterisk already running on /var/run/asterisk/asterisk.ctl. Use ‘asterisk -r’ to connect.

root@justhost [~]# asterisk -r
Unable to connect to remote asterisk (does /var/run/asterisk/asterisk.ctl exist?)
root@justhost [~]#

Now i am really confuse. Is it running or not?

There are many things you can do, like :

start or restart the asterisk service,

read the asterisk log

I type: service asterisk start
it states: Starting asterisk
I type: asterisk -rvvvv
it states: asterisk: symbol lookup error: /usr/lib64/ undefined symbol: _ast_mem_backtrace_buffer
I start researching and cannot find nothing that resembles this error message.

Does anyone know what this error message mean?

It implies you have tried to load a loadable module that was compiled with a different set of options from those used to compile the main part of Asterisk, specifically an option relating to a certain type of debugging output.

Gentleman, thank you for your help. I have managed to get asterisk/FreePBX up and running but i had a melt down. Unfortunately, i was able to at one time dial out and in, but when i did the system recording, added the IVR and set a Destination in FreePBX GUI i came across these two red messages after submitting and applying config.

I can dial out from the polycom phones to my cell phone but when i dial from my cell phone to the polycom phone it rings for about 2 seconds and disconnects. At one time it did connect and i was able to hear Hello and welcome to the Veteran’s and Community Resource Center.
