Ugh, I've learned the hard way to never update any package on a working Ast system.
Look at the bottom of your /etc/asterisk/zapata.conf
Check your signalling and echo cancellation.
signalling=fxs_ks ; X100P
echocancel=yes ; You can set this to 32, 64, or 128, tweak to your needs.
echocancelwhenbridged=yes
echotraining=400 ; Asterisk trains to the beginning of the call, number is in milliseconds
callerid=asreceived
group=1
context=default ; Points to the default context of your extensions.conf
channel => 1
Sample zapata.conf's for different setups:

I'd suggest backing up your configs, and reinstalling the system from scratch if needed. You might even putty in, nano the configs, and cut and paste.
Next time use linux personal backup appliance to image your Asterisk box before attempting updates.
