[asterisk-users] Multi Frequency Cycle Timeout - E1-R2 METROTEL COLOMBIA

[Steve Underwood]

Hi,

There are at least 2 R2 protocol variants in Colombia - one used by land 
lines, and one used by the cellular networks. Unicall implements both, 
and I think both have been used successfully by people in Colombia (I 
seem to remember debugging with people there long ago). Which is the 
protocol called "CO" in openr2?

Steve.
