I think the issue is related to the fact that the MP114 is in my case  
a combination device.  2fxo/2fxs setup.

It seems like what happens is when a call comes into the fxo it is  
inviting asterisk with the correct callerid information(sip from).   
Asterisk attempts to use this invite as a basis for a new call.

HOWEVER, for some reason or another (bug?) Asterisk identifies the fxs  
extension at the same IP address as a peer for the basis of the new  
call, and since the other peer (friend) is the FXS, the authentication  
fails, and caller ID is lost.

If I remove my FXS (friend) definition from sip.conf then suddenly all  
is well and the the callerID string is passed aok.  Of course then  
none of the phones attached to the FXS work, which is a problem...

I hope someone has some ideas on what I am doing wrong/some way to fix  
this?

Thanks in advance for any help you might offer.

This authentication is failing because of the mismatch of extensions  
described above.  The FXO is ext.  2003 and the FXS is ext. 2005.
