I was wondering why bother with this dialer thing at all :)
When you implement a new thing, it is a good idea to go back to basics and
think what you want to do.
You have multiple voip carriers and you have bunch of users. Based on the
number dialed you want to pick a carrier and dial out. May be authenticate a
certain caller for certain path. Then end of the day look for CDR's.
You do not need to set your call setup this fragmented.
How about this;
(a) User dials a international number
(b) * looks at the CallerID and Destination Number (at one database lookup)
(c) This caller is not allowed to dial this destination, so play a message
for that extent
(d) If caller is allowed, then * finds the least cost root and dial through
that path and connect the call.
* can do all these. So I would first sit and right down what I want my
system to do (in my users perspective). Then try to find a way to implement.
I wouldn't try to replace a box with another box.
my two cents ....

Though I've had implementations of Asterisk, I havent encountered this
one yet, so i'd like to seek your advise if this possible.
I would want asterisk to be stand between the dialer the destination.
The dialer will now dial asterisk access number. Asterisk will
acknowledge user by using CallerID and check against its database for
authentication and then sends out a DTMF A tone for ?? second to enable
the dialer to send the whole overseas digit.
Assume the caller is not in database, asterik could give user a busy
tone, IVR or just leave it and sends out a DTMF A tone anyway.
Once the overseas digit are sent from dialer to asterik, asterik will
then decide which telco/carrier/Voip to send the traffic to using LCR.
Please note that we need to assign at least 5-10 telco/carrier/Voip
access number for backup purposes.
Once the least cost destination is selected by asterik, asterik will
pick up the PRI line and dial a local access number and waits for a DTMF
A tone. Once the A tone is heard from telco/carrier/Voip, it will send
the overseas digit which was sent by the dialer earlier on.
Also, can asterik sends out a musical tone or IVR while connecting to
other telco to advice user that the call is connecting, else it would be
dead air from there on.
The whole process takes less than 5 seconds while the user stays on the
line for this whole thing to happen.
Thanks.
