Hey all What VoIP networking monitoring, asterisk monitoring tools would you recommend? I started working with an IT company that insists on using DSL with a Sonicwall router. The problem is that the clients are having sound problems. The owner is convinced that it's the Asterisk box. In the 4 yrs I have been doing this I have not had this bad a sound problem and it always came down to a bad setup in the Cisco router. Asterisk just doesn't have sound problems so I am going to have to convince him that its either the router or DSL. Has anyone used DSL for SIP traffic? How about Sonicwall routers?

Hi I use ADSL and SDSL on a lot of multi channel VoIP connections SIP and H323 and no real problems if you size the link correctly - this normally means limiting no of calls to match available bandwidth. Check out the upstream and downstream data rates and size on the smaller - normally the upstream. the thing that is not normally explained is the contention ratio at the local exchange. here in the UK residential broadband packages normally have a contention ratio of 50:1 so at peak you could be fighting with 49 other users. Contention ratios for business DSL packages can vary from 1:1 to typically 20:1. To monitor I use wireshark and look at packet loss on RTP. My home adsl connection is 7M downstream / 800K upstream with a 10:1 contention.I can normally get 20 x G729 channels without a problem much more and things get stressed - also I have to watch what other things are going on - downloads not too much of a problem because of the unbalanced downstream/upstream speeds but peer to peer stuff is a real killer!
