Hi,
I have found the solution for me.
So, if you have an Asterisk PBX, you have to allow the 484, because
Asterisk PBX will cancel the REFER with 484.
sip/sip_util.c
case 484: /* Address Incomplete */
case 485: /* Ambiguous */
/** @par 484 Address Incomplete and 485 Ambiguous
Similar to 404 and 410, these
responses came to a request whose Request-URI was provided by the
peer in a @Contact header field. Something has gone fundamentally
wrong, and the dialog and all of its usages are destroyed.
*/
if (method == sip_method_refer)
{
*return_graceful_terminate_usage = 0;
return 0;
}
return terminate_dialog;
If that is also interessting for the main branch, I can create an patch!
Best regards,
Bernhard Suttner
