more than 10 members in a simultaneous call queue

You have to contact the account rep - it’s a switch on the back-end they have to flip.  They will ask the usual questions as to why…  typical RC.

Good luck.

Call Queues will ring up to 20 members simultaneously.  If your account limitation is set at 10, like Joe, mentioned, call customer support.https://partnersupport.ringcentral.com/article-v2/Call-Queue-Overview.html?brand=RC_US&product=RingEX&language=en_US
