Hi All, I've a single 1.2.17 Asterisk system. Gradwell here in the UK is used for PSTN calls via IAX2. Our 'net link is a dedicated 2Mb fibre connection (of which we have ever used 50% max bandwidth). We've no E1/T1 links, everything is IP based.
My boss complains that many of the calls he holds with others has a bad quality. He also says that its not just him. My iax.conf file has: disallow=all allow=ulaw allow=alaw bandwidth=high jitterbuffer=yes dropcount=2 maxjitterbuffer=1000 maxjitterinterps=10 resyncthreshold=1000 maxexcessbuffer=80 minexcessbuffer=10 jittershrinkrate=1 tos=lowdelay autokill=yes He complains of broken audio, muffled audio, and says compared to Skype its very poor, particularly during conference calls (zaptel meetme). Most of these would be SIP based within our server though, rather than IAX/PSTN based (X-lite/SJphone). Obviously I can't do much about the far end IP connections/Mobiles etc, but what can I do to tweak/improve the call quality on the A*k box itself? The CPU stays at a constant 10% usage, mainly due to a few other monitoring apps on there (with these turned off, its < 2%, but still the same issues). Also - are there any useful stats/logs that I can examine to "see" the quality of calls?
