I really appreciate your help Ben .
To give some background of current behaviour , 1stly we are not doing
parallel forking , we are doing serial forking .
We have adjusted opensips code somehow and sorted the list of contacts
according to their registration time (*creation time column is added in the
location table for this* ).
In a branch if there are 5 contacts then we give a call to the
longest ideal contact first if that fails then opensips again try the next
longest ideal contact and so on . If All fails it gives back 500 Error .
My requirements have changed at this point .
*Agent1 call-info : sales=1,apple=20,en=5*
*Agent2 call-info : sales=15,apple=7*
*Agent3 call-info : sales=4,apple=4*
*Agent4 Call-info : hr=3,gallileo=5 *
*Invite $hdr(Call-Info) : sales,en *
*For this INVITE , Agent1 , Agent2 and Agent3 are matched candidates ** and
the elements are present in their attribute . Now the question is
who should I give the call first . *
*Here I have to calculate the average level of both the agent and which one
will be the greatest 1st call sent out to that agent . *
*When I am saying theoretically it seems achievable through config
adjustment . But the question is now how ? *
*Agent1 average skill level : (1+20)/2 =10.5*
*Agent2 average skill level : (15+7)/2=11 (Now Agent2 is in higher skill
. )*
*Agent3 average skill level : (4+4)/2=4 *
*Now the highest average skill level is Agent2 , Call will be sent out to
Agent2 if fails then will go to Agent1 if fails then will go to Agent3 . *
*Again this is a challenge for me . Is there any other module or table on
which I can save the branch with its skill level and then while sending out
call I will check the skill level and then send out . How will I achieve
this ?*
*Thanks & Regards*
