The TCP ports used by the remote engine are defined by the Microsoft RPC service.
By default, RPC uses the port range of 1024 to 5000 for allocating ports for endpoints. However, ports in this range are also dynamically allocated for use by the Windows operating system for all Windows sockets applications and can be exhausted on heavily used servers such as terminal servers and middle-tier servers that make many outgoing calls to remote systems.
These can be configured like this:
- TC/SP - All supported
Keywords: voice, engine, player, dialerls1, TCE_REM, TCRT, endpoint
