Hello I'm running chan_ss7 1.3 on * 1.4.29 and have a high load average (exceeds 1.0) with 90% CPU on Asterisk process and only around 30 calls. Load and CPU usage seems to vary proportionately with the call volume; it's no issue when there are only around 15 calls. Given the hardware (Quad Core Xeon E5504 @ 2GHz, 4GB DRAM), the G.729a transcoding shouldn't be hitting the box that hard and there isn't much else running. 1) Does chan_ss7 support the hardware echo cancellation on the Digium cards? 2) If so, how can I check that chan_ss7 is using the Digium card's echo cancellation module rather than trying to echo cancel in software? 3) Is there anything else within chan_ss7 that might be hogging CPU resources? Thanks Greg
