I have three asterisk machines and three SBCs. The cluster part is working perfectly fine but if one SBC is down, the dialplan keeps stuck for a long time on Dial. After some time, the Dial fails as CONGESTION and fallthrough takes the next one.
How can I set the time to wait for an initial reply to some seconds? The SBC has an interface directly on the same network and will reply immediately if it’s health is good.
There is a timeout option on Dial but that is used for ring timeout.
