Re: [Freeswitch-users] Dialplan bridge results in choppy audio

The call is bridged as expected, but the audio is very choppy. The first few seconds is basically inaudible, and after that the quality is better but still quite poor. In searching previous threads, I could only find audio problems related to using loopback, but nothing for the bridge dialplan tool. Also note that the ptime is 20 on both legs.

These are virtual machines. Would this have a negative effect? On 3:59 PM, Peter Olsson wrote:

Yep. When you are virtualized, both the timer that handles the media is affected, and having the processing power to handle the media it at the mercy of the other processes. OpenVZ supposedly provides the best timing.. or in xen 1000 mhz kernals.. but still... if you have a performance issue with something like this, it's probably due to the virtualization. Try it bare-metal and see if you have the same problem. Is there much load on this box? -Avi On Wed, Mar 14, 2012 at 2:42 PM, Adam Kelloway <adam.kelloway@newpace.ca>wrote:

Thank you both for the clarification. Both of the VMs I have freeswitch on are run from the same box, which also runs a number of other VMs with other applications. This is not a production environment, however, so there is virtually no 'call load'. I will see if I can test it out on real hardware, thanks very much. Adam On 3:59 PM, Avi Marcus wrote:
