[Spce-user] spce caller name peered with Asterisk/FreeSwitch

especially if it is in proxy config, then it could be somewhere here:

...
if($fn != $null && avp_check("$fn", "re/^\"?\+?[0-9]+\"?$"))
	{
		$avp(s:caller_cli_userprov) = $fn;
		avp_subst("$avp(s:caller_cli_userprov)", "/^\"?([^\"]*)\"?$/\1/");
	}
else
	{
		$avp(s:caller_cli_userprov) = $fU;
	}
....

I guess (really my guess!!!), that the last line could be set to "$fn"...

else
	{
		$avp(s:caller_cli_userprov) = $fU;
	}

I'm really not sure! and don't know SPCE in details, it may cause some 
other problems...

Sorry if I'm wrong!
