Commio is a SIP Proxy and therefore a wide variety of signaling can come back to your network from us, whether it is sourced directly from Commio or from a downstream vendor. There can be a wide variety of reasons that come with a code depending on how the source switch has configured it. For example a 503 could list "Route Not Available" or "Funds Required", etc.
Below are a list of codes your switch should be programmed to advance on. In general you should be set to advance on any 4XX or 5XX code received. One firm exception is "487 Request Terminated". Two optional exceptions would be "404 Not Found" or "486 Busy".
403
404
407
408
410
480
482
484
486
500
501
