[Asterisk-Users] "Glare" condition - How well does asterisk handle?

[Scott Stingel]

A little more research on this:

I found a Dialogic flow diagram that seems to indicate what happens when
glare occurs on an IDSN line.  So it looks like perhaps it can occur?
Re-phrasing my original question:  "Does the asterisk PRI driver properly
re-try an outgoing call that is dropped due to a glare condition?" 

Note the chart entitled "Glare (call collision)":

Hi-

I have an upcoming application that requires use of PRI channels that are
primarily used for high-volume incoming traffic, but that are to be used for
outbound calling as well.  Of course, one option is to have dedicated
outbound channels reserved, but this is an inefficient use of channel
resources.

Normally PBX's are designed to have the CPE yield to an incoming call if a
particular channel is seized by both ends at the same time (a condition
known as "glare"), but I'm wondering if anyone has real-world experience
with asterisk to say how well this is handled.

Thanks
