[Freeswitch-users] Redundant Dial Plan in JS

[Sean Devoy]

Thanks Ken.

 

I am left with a few questions though.  If I use:

<action application="bridge"
data="sofia/gateway/primary/dialstring|sofia/gateway/secondary/dialstring"/>

 

What happens if the destination number is just plain old BUSY?

 

Does the dialing user hear the fast-busy signal from "primary" when their
route is defective and then hear the ring from secondary?

See

lover

Or see using the bridge command in conjunction with the continue_on_fail
channel variable...

This is pretty easy to do... Keep in mind that what good ol' ma bell does is
try one route and then if it fails, try to re-route around that... That's
all the above is showing you how to do

Hi,
 
This question stems from the fact that I cannot find a VOIP Service Provider
(VSP) that can connect outgoing calls truly reliably.  I have customers who
expect calls to go through just like good old ma-bell did -100% of the time
barring natural disasters.  You have to admit those guys set the bar pretty
high for us.
 
I was using Voip Innovations with decent success, but my users complain
every 2 weeks or so and I send the trace to VI. The standard response is
always "We have updated our route tables for that area."  I switched to
Vitelity where I was assured they have redundant paths and this could never
happen!  I have only confirmed it happening twice in the last 3 weeks!  Of
course one of those was during the demo of the new service I had just
installed for a new customer. 
 
So, I give up.  My new approach is "VSPs cannot deliver consistent highly
reliable service - work around it!"
 
I know I want a dial plan that will check the bridge status and redial using
a different gateway (VSP) if it failed (not busy or no answer - failure).  I
am pretty sure the best/easy approach is a JavaScript "dialer" script to
handle this.
 
I have looked in the wiki for such a sample.  If it exists I have missed it.
So rather than "re-inventing the wheel"  I am reaching out to you all.  Does
anyone have a dialing script that checks for failure and redials on failure
or just continues to voicemail on no answer?  I will happily test and tweak
it and add it to the wiki if you have something to get me started!!!  If not
I shall take the plunge and get started! My ideal solution will dial, play a
message and redial on failure, maybe 2 or three times or play a failure
message and email me on excess errors.  I am leaning toward "Call
congestion, rerouting.  Please stand by"  while the new bridge is being
attempted.
 
Thanks,
Sean
