<p class=MsoNormal><span lang=EN-US>Hello.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Could someone please explain the idea
behind WaitExten implementation? I was wondering how is it possible for this
application to work at all because it always reads only single digit and then I
discovered that actually most of the job of collecting digits and jumping to
extension does __ast_pbx_run. I probably do not know the whole picture but to
me it looks like the only reason why digit collection is performed by code “outer”
to WaitExten application is to allow different application contribute into
collection – that is Background detects first digit, WaitExten detects
the second and __ast_pbx_run collects the rest.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>To me, more consistent approach would be to
have digit collection buffer inside a channel structure and allow applications
to append there and/or use data from the buffer. This way Background would
append detected digit to a buffer while WaitExten – appending more and
checking if it has non-ambiguous match. Another benefit of such an approach
would be the fact that Read application also gets ability to use digit pressed
during Background (currently it does not).<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Any thoughts?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Regards,<o:p></o:p></span></p>
