Im having trouble doing an SIP trunk from a ring central number into Retell. Ive tried to do it but the credentials dont match on either end. Curious if a way exists or how we could integrate a number from our ring central domain into retell

It sounds like the SIP trunk authentication details (username, password, domain, or transport settings) between RingCentral and Retell aren't matching, which is often caused by incorrect SIP credentials or unsupported trunk configurations. Have you checked whether you're using RingCentral's SIP Connect credentials and what specific error message Retell is showing during the connection attempt?
