[Jerome SOUCANY]

Hello,

I changed these parameters in zapata.conf :
callprogress=no
busydetect=no

And now it's working fine.

Objet : [Asterisk-Users] No sound on 10% of incoming calls

Hello,
 
I have a problem with Asterisk, on 10% of incoming calls the IP Phone ring
but I don't hear the caller and the caller doesn't hear me (all IP Phones
have the same problem).

This problem appear also if the call is directly send to the second E1 of
the digium card who is connected to an IVR.

It does not depand on the charge of the server (I have the problem with only
one call).

The configuration :
 
PRI (France Telecom) 15 channels  <====> Asterisk <=====> IP Phone
 
* 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

* IP Phone :
	SNOM 320 (latest firmware)
