Thanks for your answer. Googling in the lists I found what you are
telling that maybe there is a synchro problem with the E1, but I'm not
so sure that this could be. I am configuring zaptel.conf like this:

span=1,0,0,ccs,hdb3
bchan=1-15,17-31
dchan=16

But I also changed to test to:

span=1,1,0,ccs,hdb3

The same thing happens.

You may consider also that if I connect PAP2 to LAN everything works,
also if I use other ip phone from internet works fine.

I also check if I'm loosing interrupts and everything seems ok. Also I
pull out the TDM400 from the box.
At last I change jitterbuffer=16 and it works better, the clicks are
reduced. Could this be possible? What is the function of this parameter
in zapata.conf?

I should tell you that the TE100P is connected to another E1 board (not
a live E1) from Natural Microsystems which acts as a gateway to PSTN.
This board works as a PRI master but I don't think that this could be
the problem as long as using other phones or in LAN it works perfectly
and the voice is clear with no clicks o sound looses.


Thanks again,


Alejandro
