For those who don't know the meaning of BRS: it is Best Route selection.

This is a special routing algorithm in Mizutech softswitch. Unless LCR (least cost routing) this will check also the quality (ASR, ACD and other statistics)

Regarding your question:

It would be important to know the statistics and pricing on both of your routes. If possible, please send a remote desktop access to support@mizu-voip.com and my colleagues will verify this.

Otherwise you can't expect too much from BRS after only 30 calls. Usually it needs at least 50 call for more stable statistics.

Please note, that this module will check both long and short time statistics (even 1 month old statistics are considered ...with lower priority)

In the MizuManage you can find a helper application named BRSDemo.exe. You can experiment with that application to see how the BRS would route the traffic under different circumstances.
