With a virtual CSR that has a specific throughput (e.g. CSR with 1000kbps throughput) how do I determine what message is sent back to the ITSP when the throughput limit is hit and no more calls can be accepted, when the ITSP endpoint is configured for more SIP channels than the CUBE throughput allows? Trying to find out if it would be a 408, 480, 503 - something that their endpoint can then hunt on.
Thanks.
Nathan.
