Making calls from a Patton FXS line my ITSP (voip.ms) was giving me reorder 
tones (as audio) to some numbers due to my inside CID being sent to the ITSP.

The inside device causing trouble was sending a From with its IP address rather 
than the sipx machines domain name, I fixed this and all is well now.

My question is: shouldn't *all* outbound calls through a gateway have their 
'From' remapped based on the gateway settings?

I've gathered traces/pcaps while tracking this down, if there's interest in a 
JIRA (and its not just my flawed expectation) I'll fill one out.

-Eric Varsanyi

Details and environment:

My inside CID in the initial invite from the device (a patton FXS) is:

From: "UL Cordless" <sip:[email protected]>;tag=6d8832c57a
To: <sip:[email protected]>

After going through the registrar and the the proxy it comes out of sipxbridge 
toward the ITSP as:

From: "UL Cordless" <sip:[email protected]>;tag=2849050422005484683
To: <sip:[email protected];user=phone>

Calls from my polycoms do not do this and instead send the configured callerid 
I put on the gateway page, the difference is they do not send their IP but 
rather the official 'domain' in the From:

From: "Office 3" <sip:[email protected]>;tag=6F88CA59-A255167C

this is transformed for the ITSP to:

From: "E Varsanyi" <sip:[email protected]>;tag=8343318532040437072

The gatway to voip.ms is set up with 'Default Caller ID' blank and the 'Specify 
Caller ID' fields set up with the CID I want to send outbound as shown on the 
wiki:
