Thanks for the description Jim. Why does the g729 codec show 2ms when Asterisk is restarted while other times it can show something as high as 4000ms? This is all under no load at all when this happens or simply a call or two. Once Asterisk restarted, all works fine. The following is the cpu info (this is an amazon instance): [r...@ip-10-251-69-209 ~]# cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 65 model name : Dual-Core AMD Opteron(tm) Processor 2218 HE stepping : 3 cpu MHz : 2600.000 cache size : 1024 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu tsc msr pae mce cx8 apic mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt lm 3dnowext 3dnow up pni cx16 lahf_lm cmp_legacy svm cr8legacy ts fid vid ttp tm stc bogomips : 5202.13
