[Asterisk-Users] Busy problem

[Jerome SOUCANY]

Hello,

I have a busy problem with Asterisk when I try to transfer a call from PRI
directly to IVR.
This problem appear sometime after 2 hours or 2 minutes.

The log file contain :
Unable to create channel of type 'Zap' (cause 34 - Circuit/channel
congestion)

When this problem appear I must restart Asterisk to solve it.

Another thing, I don't know why the alarm is set to NOP on SPAN 2 ?    Maybe
it comes from here ?

Any ideas ? 

The configuration :
 
PRI (France Telecom) 15 channels  <====> (SPAN1) Asterisk (SPAN2) <=====>
IVR
 
Server : 
        - Dell power edge 1800SC
        - 2 Ethernet cards (LAN + VoIP LAN)
        - Digium card : TE 405P
        - Linux Mandriva LE 2005 (10.2) :
          Linux ASTERISK 2.6.11-12mdksmp #1 SMP i686 Intel(R) Xeon(TM) CPU
3.00GHz unknown GNU/Linux
	  - Asterisk 1.2.4
        - Zaptel 1.2.3
        - Libpri 1.2.2
