Problem with maximum number of parallel calls limit

Thirdlane platform General Questions

Hello,

i have ThirdLane MultiTenant PBX and i want to limit the maximum number of parallel calls.

I did the following settings in the ThirdLane PBX Manager 6.1.1.12 GUI:
1. Tenant Management -> Tenantname -> Maximum number of concurrent calls: 2

2. PBX Settings -> Global Variables -> TL_ENABLE_MAXCALLS_CHECK 1

After that, i tested 3 parallel calls and it worked fine but i want to limit the parallel calls to 2!

What is the problem?

Best Regards!

Set the calls on each extension. If you change the max concurrent calls on the tenant it will then set that limit on new extensions. I think you may have added the extensions then changed the limit on the tenant.

Ok the max. concurrent call limitation works, BUT i have the following prblem:

example: 
Option max. concurrent calls: "2"

When all 2 channels are used (2 active calls) and i get a third incoming call, then i get the info "all lines are busy". How can i define, that the third call will be forwarded to an external number, a voicemail, or anything else?

Best regards,
Lukas

I think, huntlist is not the solution?

Following example:
- A company with 5 Extensions (10, 11, 12, 13, 14).
- I get an incoming call to extension 10 -> ok
- I get a second incoming call to extension 11 -> ok
- I get a third incoming call to extension 12 -> this third call should be forwarded to an external number or a voicemail, or anything else. 
I only want 2 separat incoming calls.

What is the solution for that example?

Best regards,
Lukas

you cant

limiting concurrent calls to 2 is exactly that. Forwarding a number isnt limiting the calls and therefore not the purpose of the code. The purpose of the code is to create a solution similar to the old analog lines. If you have 8 copper lines, you need to have a free line available to forward that call out on the other channel. Therefore not only will you not receive that 9th call if all 8 copper lines are in use, but you dont have 10 lines in order to forward a 9th call out anyway.

In most situations your carrier will double up your billing rates on forwards anyway. You're paying in minutes or price-per-minute for the incoming call, and also deducted separately for the forwarded calls duration. Unless you're able to track both calls in your CDR (the thirdlane CDR wont write two records because its  a single bridged call) then you could be exposing yourself to accounting errors when doing profit and loss analysis.
