Summary:                    call drop aleatory and aparently not a irq issue
Description: 
I have the following arquitecture:
Asterisk with 2 E1, both are PCI express, so there wouldn`t be IRQ
issues.

I have my Asterisk 1.6.2.13 conected to a switch and my softphones and
hardophones connected to another switch.

What happens is that calls drop suddenly ramdomly. We have some sound
quality issues but don`t see errors other than some:

channel.c: Dropping incompatible voice frame on SIP/XXXX-0000326f of
format alaw since our native format has changed to 0x4 (ulaw), 
but this messages happen at all times and not when the call drop happens.

We are suspecting some problem with SIP protocol.

We are ataching full and the part where the call hangups.
