This means it's used only if the via branch parameter _does_ _not_ start with "z9hG4bK". If the transaction is 3261-style, the via1_matching parameter is _ignored_. In your case the branch parameter does start with "z9hG4bK". > What could be wrong?<br> The CANCEL via branch does not match the INVITE, so the CANCEL is not matched to the existing INVITE transaction. You need to fix your user agents.
