[Freeswitch-users] Use rates from lcr in nibblebill module

Update the to the latest.  I've added more channel vars:


after doing:

        <action application="lcr" data="12148267722 default2"/>
(not a real number)

I get the following:

variable_lcr_query_digits: [12148267722]
variable_lcr_query_profile: [0]
variable_lcr_query_expanded_digits: [12148267722, 1214826772, 121482677,
12148267, 1214826, 121482, 12148, 1214, 121, 12, 1]
variable_lcr_rate_1: [0.01000]
variable_lcr_carrier_1: [teliax]
variable_lcr_codec_1: [PCMU]
variable_lcr_rate_2: [0.01440]
variable_lcr_carrier_2: [vitelity]
variable_lcr_codec_2: [PCMU]
variable_lcr_route_count: [2]
variable_import: [lcr_carrier,lcr_rate]

which, I think is what you are asking for.  If you know which route you are
going to use (eg: 1) then you can get it's rate by using lcr_rate_1.

Alternatively, you can use the lcr_auto_route and then once the b-leg
connects, query the b-leg variable for lcr_carrier and lcr_rate to see which
one was actually used.

You really can't use lcr_auto_route and set a single rate since each leg can
be rated differently (look at example above).

Normally lcr is used for your own rates between you and your carrier.  That
is independant of the rate table used for your customers.  You can use lcr
to query both.  First use lcr to query your own rates using a different
profile.  This would return a *single* route if you setup your route table
right.  Save the rate in a var to be used with nibble bill.  Then use lcr
with your external rates so you can route according to your own cost with
your carrier(s).
