Can anyone explain exactly what this parameter does? The documentation suggests that it has to do with the time between rings on an FXO port configured for plar opx connection, but as far as I can tell the FXO call detection does not work this way. It appears that IOS sets a single call timer when an FXO port starts ringing and after this time expires subsequent ringing is taken as a new call. Worse, caller ID information is forgotten at this point so the "new" call is anonymous.
I can't tell whether the time set by "timing opx-ringwait" is used for the call timeout, but it seems to affect it. Unfortunately it cannot be set to more than 10 seconds and I would like calls to be able to ring indefinitely (and certainly more than 10 seconds). Timeouts ringing infinity doesn't do it either.
