I have the same problem using chan_ss7 1.3 (high load). I had no problem 
witch previous versions of chan_ss7, so mayby new version cause such a load?

Subject: chan_ss7 and echo cancellation


| 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
