I just change in iax.conf in [general] section: 
from:
allow=all

to:
allow=ulaw
allow=alaw

Codec and with Asterisk 1.4.39 is working but CallerID is working as well.

Can someone explain to me how changing in allow=ulaw/alaw in iax.conf effect the display of incoming CallerID from PSTN line.
My AudioCode gateway communicate with asterisk server using SIP, so why changed to iax.conf affect sip communication? 

So how did it happen?  It is good, it is working but can someone with more knowledge explain us WHY?  
As I'm sure I'll not be the only one with this problem of CallerID.
