asterisk users - Dec 2003 - Outgoing call with bad/choppy sound

Hi all.

    I have this configuration:


Telco <-----(E1)----->TE410P//Dual Xeon Server 
2.4Ghz<-----(Ethernet)----->Switch<----->GS//BT

    The Server is running RedHat Linux 8.0 with kernel 2.4.18-14-smp and 
we are having the following 2 issues:

    1.- When making calls from the GrandStream to the PSTN the audio is 
choopy, plus theres is a pulsing sound, but when the GS receives calls 
it sounds great.

    2.- We are not receiving any callerd id from the PSTN, this may be 
an issue with the E1 provider, will checkit, but again, it might not.

    Thank's in advance for any help.

I have the exact same problem with the choppy sound when a call is 
originated from the GS phone to the PSTN (X100P).. Recieving calls if 
fine and calling other extensions is fine.. I have had this issue for a 
while now and have not been able to solve it.. I have tried beta 
firmware on the GS phone and I have kept to the latest asterisk CVS 
version but the problem remains.. Hopefully someone will have a solution..

Later..
