[Asterisk-Users] Asterisk can't create Zap channel - nightmare

[Ing CIP Alejandro Celi Mariátegui]

I have the same problem, I have 4 X100P (FXO) with 4 external lines
(hunting lines), and Asterisk runing on FC3.

Sometimes when 1 or 2 persons are using 2 lines, when I try to make a
call, I receive this message.

        May 17 13:18:53 NOTICE[1857]: app_dial.c:749 dial_exec: Unable
        to create channel of type 'Zap'
          == Everyone is busy/congested at this time
        
I look on zap show channels and zap show channel X and no problem. The
idea is that you can take any of the 4 lines.

But when i can't make a outbound call, if we receive a call, the call
was received good by the Asterisk.

        May 17 14:20:37 NOTICE[6969]: chan_zap.c:5367 ss_thread: Got
        event 2 (Ring/Answered)...
            -- Executing Wait("Zap/4-1", "1") in new stack
            -- Executing Answer("Zap/4-1", "") in new stack
            -- Executing DigitTimeout("Zap/4-1", "5") in new stack
            -- Set Digit Timeout to 5

            -- Executing BackGround("Zap/4-1", "vm-inicio") in new stack
            -- Playing 'vm-inicio' (language 'en')

and the call success!
