<tt>Hi Andrei,<br>
<br>
Do you use TH without dialog support right ? IF so, try with
dialog support (just create the dialog before doing TH) - this
will shorten the "did" param A LOT and maybe Cisco will not
discard it.<br>
<br>
Also, do you obfuscate the Call-ID too ? if not, with dialog
support, you may try to use dlg_match_mode [1] with 1
(DID_FALLBACK) to try a SIP matching if the DID param is matching<br>
<br>
