jlumby Posted September 5, 2009 Report Share Posted September 5, 2009 I have been noticing that certain situations cause a long delay in the audio between two parties, and I was wondering what may cause this. It seems that the more legs that are involved in a call, the longer the delay gets. For example, if an extension calls an extension on another PBX that is directly networked to it, then the call is usually fine, however if it forks to the cell phone, then there is a couple second delay. However however if that same extension calls the cell directly (utilizing the same PSTN gateway, just not forking through the second PBX, then there is no noticeable delay) Since it does not happen with every call, I am wondering if adaptive jitter buffers are being additive. Most all of the links in this example have a fairly consistent latency of ~ 50ms, however I have seen occasions where the latency might jump to 120ms for one instant within the total duration of the call. Does this cause the jitter buffer to increase, and never decrease again for the duration of the call? We are not having any noticeable audio issues such as cutting out, dropping, or 1 way audio. Just looking for some input as to how I can fix the long delay that does not happen all the time. Quote Link to comment Share on other sites More sharing options...
