It's likely that you already thought of this but I'll ask just in case.
Is it the same access code for every call? If so, have you considered just
making that part of the dial string? That way when your users dialed a PSTN
number, the next thing they would hear is the ringing of their called party
and they wouldn't have to concern themselves with any of it. It would be
just like the old Hayes Modem days of "ATDT *70,,4165551111" where commas
cause a pause in dialing. In Asterisk I think it's a 'w' for a pause.
When someone dials a pstn number, like 416-555-1111, you would acually dial:
<gateway number>ww<access code>ww<4165551111>
Thanks Dave. That is an option, and what I hope to do eventually, but
it's been tried and found not to work with this setup. This was the
subject of my mail a few weeks ago. It's particularly galling that they
ancient Hayes modem - closed-source, properietary, could (ahem) reliably
detect secondary dialtone, whereas Asterisk, the gem of FOSS VOIP, has
not capability whatsoever to actually detect secondary dialtone. It
sounds like it should be a "simple" Application to write, but if it were
that simple, somebody "woulda".
And, incorporating the dial string like that doesn't really solve the
problem - once connected, people often have to deal with interactive
DTMF-based systems, and they run into the same problem.
Cheers
Ian
