[asterisk-users] DAHDI Error

[deeps backup]

I can dial after 1-24 channels but getting intermident problems dialing to
DAHDI channels. Calls get connected sometimes but fails sometimes with below
error.

 app_dial.c:1747 dial_exec_full: Unable to create channel of type 'DAHDI'
(cause 34 - Circuit/channel congestion)

I can't figure out the issue. Any suggestions please?
