Yajie, the way most ip systems work is it will take the digits before passing them to a line, and the dialtone is something that is generally generated by the pbx, to rule out that its the pbx causing the stutter and not the analog line try connecting directly to the analogue lines with a regular pots set.
If its not exhibiting the same sympotoms at that point, I'd look for something in the aastra settings; something along the lines of a line identification method (perhaps there is an audioable differentiator they have programmed into there pbx so you know its going out on pots?) Failing this Aastra's tech support is always pretty friendly. Just give them a ring :) Phil ________________________________ From: Yajie Si [mailto:[email protected]] Sent: Tue 8/18/2009 9:22 PM To: [email protected] Subject: Re: [on-asterisk] the stutter tone issue on fxo lines Hi Philip, Thanks, it is not the voice mail. The stutter tone (or more precisely two short tunes) are there whenever you dial out using FXO line, but not when you use IP lines. And it is not right after you pick up the handset, but after you dial the digits and press the dial button (Aastra phones have dial button).
