[asterisk-users] op_div: non-numeric argument

[Positively Optimistic]

Ladies, Gentlemen

We are experiencing an unusual problem in our asterisk 1.4.34..  We are
attempting to determine if channels are in use before paging to them.

This works correctly, as in it pages the phone..  however, we see the error
message below on the console...  after googling, we discovered limited
information regarding the issue...
