asterisk users - Mar 2007 - Issue with Calling Name ID in SIP: Asterisk sets Caller ID Number as Name if NO Name

Hi,

fyi, I use Asterisk 1.2.9.1
In some scenarios, we receive call from PSTN without Callerd ID Name (which
is normal).
I would like to transfer this call to another softswitch. Again, I would
like to let this this CallerID Name Empty.

If I look at the logs, I can see

    -- Executing Macro("SIP/localdomain.com-b79242f0",
"set-callerid-name")
in new stack
    -- Executing Set("SIP/localdomain.com-b79242f0",
"CALLERNAME_TMP=") in
new stack
    -- Executing GotoIf("SIP/localdomain.com-b79242f0",
"1?format_empty|1")
in new stack
    -- Goto (macro-set-callerid-name,format_empty,1)
    -- Executing Set("SIP/localdomain.com-b79242f0",
"CALLERNAME=") in new
stack
    -- Executing Goto("SIP/localdomain.com-b79242f0",
"set_callername|1") in
new stack
    -- Goto (macro-set-callerid-name,set_callername,1)
    -- Executing Set("SIP/localdomain.com-b79242f0",
"CALLERID(name)=") in
new stack

So, it should be alright!
Then I forward the call:

    -- Executing Dial("SIP/localdomain.com-b79242f0", "
SIP/990003726831598@<next-hop>|30") in new stack

And if I look into SIP debug mode:

As you can see, name is set ! eventhough callerid(name)= ....
Is it a bug ?
How can I really clear this callerid(name) ?
How to prevent Asterisk to put back as Name, the number ?


Thanks for your kind return !

Regards,
