I have always experienced very good call quality via my asterisk server snom phones. With soft phones especially on mobile (sipdroid or asip) quality is poor. With commercial sip services on my mobile - that do not of course use my asterisk server but use the same good wifi connection - quality is very good and much better than I achieve with a sip client pointing to my own server. Are there some things that I could be missing on the asterisk configuration that could improve the call quality for sip clients on mobile device. -- - Eric Smith
