234 Internal Loop

You have misconfiguration which creates internal loop.

SOLUTION: fix configuration to avoid loop.

Very often this happens with improper IVR configuration, which creates such loop: DID -> IVR -> DID -> IVR, etc

Another case can be with IVR for unauthenticated calls, which routes call to any other IVR, but because this call is unauthenticated, it ends up in initial IVR creating a loop.

Example of IVR loop:

DID (2222) -> IVR (name: Loop) -> Transfer to DID (2222) -> DID (2222) -> IVR (name: Loop) -> etc
