[asterisk-users] Adding Congestion to CDR logs

[Kenny Watson]

Hi Gareth,

The problem I have had in the past with providers is either that the registrar is still up and its further down the line in the provider that the call is being congestied, so the qualify doesnt work!

or that the providers registrar has issues but the rest of their services is up so the qualify shows the peer as down but it will still process calls (I disabled qualify for this provider).

How much load would adding agi in produce, I'm processing about 2000 call attempts per hour which is going to possibly double on this box.  I've been trying to keep things as light as possible.

If I can get congestion into a cdr and have it sending cdr off to a SQL db it would be ideal.


Thanks

Kenny

Yes you could certenly do that. If one of your sip providers goes down 
and you have qualify=yes for them then the call should fail immediatly 
and you can detect the return code and automatically fail over to a 
different provider.

A better way would be to make use of AGI and write code to lookup calls 
costs for the specific destination so you can perform least cost routing 
between your providers. When the call is hungup you can record stats 
about that provider such as if the call failed.
