Using two yeaster Gateways with grandstream 6204


I have 8sims yeaster gateway setup with grandstream UCM 6204. Both inbound and outbound working perfectly. Please how do I add another 8sims gateway to the present system setup to make agents count 16. Meaning two trunk working simultaneously with the UCM. Hoping someone will reply soon. Thanks


Hello dear,
gateway is voip?
if voip add another voip trunk between ucm and yeastar gateway.
and add the voip trunk of the second yeastar gateway to the existing outbound rule, and add a inbound rule to this new gateway.
