[Freeswitch-users] openzap Failure opening channel error

[lakshmanan ganapathy]

Hi,
Again I was struck in a problem, Here is the scenario.

On incomming call, I just call an event outboud socket. But what happens is,
for the first 15 call, it is working fine. But from the 16th call to 30th
call, it says the below error.

But for the next call, when it is opening channel 1:1, it is executing my
dial plans.
I don't know why it failed when it is choosing 1:17-1:31. Any one has any
idea.

Below are my configuration details:

openzap.conf
[span zt PRI_1]
trunk_type => e1
b-channel => 1:1-15
d-channel=> 1:16
b-channel => 1:17-31
