Same Code Point on two Virtual Machine (IP)

[mehdi]

Hello,

Is it possible on Mobicents to have on two Virtual Machine (two IP), the same Code Point => the PTS in front of the two VM will do the loadsharing algorithm. 

I try to do this, when i start VM1 or VM2 regardless; i had no problem and the callflow is OK

when I start both, the second one had a stack trace

and the callflow on the second VM is KO 

Thanks in advance.

Has someone any idea ?

Thanks in advance.

Best Regards.

Hi Mehdi,

 

Yes you can have that setup, but for making them work simultaneously in active-active mode you need a proper license on each instance.

 

Best regards

Hello Mehdi,

I think it is achievable if you configure a proper STP before your both SS7 stacks. That STP will loadshare traffic depending on SLS. Pay attention that your two SS7 stacks must have some different point codes and the STP must have a that point code that is "same Code Point".
