[Asterisk-Users] zaphfc problem

[Arnaud Pignard]

Hi,

I have a partial working installation with zaphfc.

Incoming call :

For incoming call, seems work fine. But the sound is very bad with bounce 
short crashing sound. Same sound with echo cancel off or on.
SDA work fine.
Another problem, it's seems that's zaphfc don't reset correctly the line. I 
have one of my D channel how was busy even after stop communication.

Outgoing call :

When try make a call, i have error like this :
Mar 18 22:44:05 WARNING[229391]: chan_zap.c:5952 zt_pri_error: PRI: !! Got 
reject for frame 1, but we have nothing -- resetting!
MFE for TEI = 80
   == D-Channel on span 1 up
   == D-Channel on span 1 down
   == D-Channel on span 1 down

Config is mostly like howto on voip-info.org

in /var/log/messages, i have hundred of this line :
zaphfc: empty HDLC frame received
