That won't work 'cause you are limiting on the general TESTGW for realm and resource. You need to find out which resource distributor gave you and then use limit_execute and the actual resource name (GW_001 or GW_002). As you can see, without changing how distributor works this will be full of race conditions. ie: you can get the resource by expanding ${distributor(aa_rr)} and then using that in limit_execute, but since distributor has no knowledge of limits it may continue serving up a resource that has reached it's limit. And even if distributor knew about limits it would have to reserve the resource and then *use* the resource right then not pass it back as a string. That changes how you use distributor. Kind of a pain. A bit more heavy weight, but maybe look at using mod_lcr with limit support? On Tue, Oct 5, 2010 at 9:26 AM, Frank Ochere <ochere@gmail.com> wrote:
Hello,
I have the following in distributor.conf.xml
<list name="aa_rr" total-weight="2"> <node name="GW_001" weight="1"/> <node name="GW_002" weight="1"/> </list>
in dialplan
<extension name="TESTGW"> <condition field="destination_number" expression="^7777(\d+)$"> <action application="limit_execute" data="hash TESTGW TESTGW 1 bridge sofia/gateway/${distributor(aa_rr)}/$1"/> </condition> </extension>
my question is, is it possible to use limit_execute and distributor concurrently as in TESTGW above? ie limit calls to 1 per gateway but being alternated as specified in list aa_rr
