If the sender changes its Synchronization Source (SSRC)
identifier, you will be asked whether to ignore this change.
•
If you choose Yes to ignore the SSRC change, the call will
stop.
•
If you choose No to accept the SSRC change:
a
The FrameScope Pro adds the new SSRC to the members
and senders tables.
b
The FrameScope Pro validates the new SSRC, as
described in RFC 3550.
•
If the new SSRC is valid, the FrameScope Pro
terminates the current session and starts gathering
statistics for the new session. The old SSRC is removed
from the members and senders tables.
•
If the new SSRC is not valid, the FrameScope Pro
continues to gather statistics for the original session, if
the session has not timed out.
Once the test stops, press Details to view the SIP signaling log.
