Summary:                    Calleer don´t hear the called channel
Description: 
When I call directly from my phone connected on TDM2400 I can´t hear the
called part, but I can hear them. No errors on CLI and messagens from
log...
But happens something strange, when I call from a SIP Channel (like
GXP2000 from my secretary) and this call is transfered via atxfer for any
channel connected on my TDM2400, it´s work normally. This happen only when
I call directly from any channel connected in TDM2400. This started happens
when I upraded from zaptel 1.4.9.2 to DAHDI 2.2.0.2, and asterisk 1.4.26-1
. I tried to remove echo cancelations, but no success. I can´t reproduce
if is problem from DAHDI or new version from Asterisk ...I was using the
1.4.25 version.

All channels are happening this.

Hi, I got the real scenario when this happens, only when I call directly
from my FXS channels directly to E1 card manufactured by Digivoice (model
VB6060), when I call from FXS (TDM2400) to FXO (TDM 400) it´s works great.
I made contact with Digivoice Support, and he ask to me to downgrade to
dahdi version 2.1.0.4, but I didn´t have success to compile this version
on my system. My doubt it´s if is a problem with DAHDI (when I had Zaptel
1.4.9.11 that´s not ocurred this problem) or Digivoice software.
No errors or warnings happens in any log file, verbose or debug. 

When I made in the other way (Digivoice to Digium) I don´t get this
problem, only happens with Digium to Digivoice.

My System:

Slackware Version 11
TDM2400 with 24 FXS modules
TDM400 with 4 FXO modules
E1 Board Digivoice Model VB6060 (www.digivoice.com.br)
Voicerlib 4.2.0.0 (Interface for VB6060)
DGV Channel (Channel driver Digivoice to Asterisk)
Asterisk 1.4.26-1
DAHDI-2.2.0.2 (Tools and Linux)

Sorry if not reproduce a bug in DAHDI version.

Thanks
