The following is an RFC 5057 snippet which indicates that it unclear why someone would return such a response. Thus you'd likely need to ask the vendor concerning why they are sending it. "(7) 480 Temporarily Unavailable: RFC 3261 is unclear on what this response means for mid-usage requests. Future updates to that specification are expected to clarify that this response affects only the usage in which the request occurs. No other usages are affected. If the response included a Retry-After header field, further requests in that usage should not be sent until the indicated time has past. Requests in other usages may still be sent at any time." _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
