What means error "A key that was used to sign the route set is no longer valid" ? RRS feed

  • Question

  • I have two SIP clients that are in long call through Lync server. After 17h user press HOLD, but server responds with "Route set is no longer valid. A key that was used to sign the route set is no longer valid".

    Could someone point me to document with description of this error ? or please tell me which key is invalid or why this happens ?

    Response from Lync:

  • I am facing the same issue while doing a mute in a a Lync Centralized conference. Looks like this has been happening from RTC/4.0 (I am running it on a Lync 2013 server RTC/5.0)

    If I do it the consecutive time, the Info gets accepted with a 202 response and then, I receive a success response from the server.

    The difference between both the INFO requests are only in the branch argument in the Via header and Authorization parameters such as crand, cnum and response challenge. These are anyways bound to change for subsequent messages. Can anybody confirm if this is an error with the Lync server ?
