<br>Depending on what telco Charlie is connected to would change the CallerId presented to Charlie from being Alice's or Bob's Cid.<br><br>When a call is forwarded, Charlie's telco receives different ANI and CID : some (seems to) favor ANI and some CID.<br>
<br>An interesting thing to test is to let Bob issue a simple call to Charlie using a fake CID such as 0123456789.<br>Will Charlie's phone display this non-existent number or not ?<br>
</blockquote></div><br><br>Another trap is recently discovered is :<br>sometimes, the call is presented to Charlie with Alice's name and Bob's number !!<br><br>I met this one when Charlie is subscribed to an analog line with Caller Name Service enabled.<br>
For a reason I don't know, it seems that the numbers choosen to display the name and the number are different (ANI and CID).<br>
