<div dir="ltr">Hi all,<div><br></div><div>I have recently integrated CUCM v9 with an Ericsson MD110 which is working without issues. The integration is via multiple E1s to a gateway which is controlled by CUCM using SIP (well SIP trunk between the gateway and CUCM... you know what I mean). Because the E1s from the MD110 were previously connected to the PSTN the client blocked all calls out using the privacy flag on the outbound SETUP message (e.g. Calling Party Number i = <b>0x01A1</b>, '<i>DID_number</i>'). Now that these E1s are used to pass calls between the MD110 and CUCM they want to be able to have caller ID between the 2 systems. Is there a way to override the privacy flag on the gateway and send the calls to CUCM via the SIP trunk with caller ID?</div>
<div><br></div><div>I would imagine there is something I could put on the serial interface to bypass the privacy flag but I'm out of ideas.</div><div><br></div><div>As you probably guessed the client has no in-house programming skill at the level to make the required changes in the MD110 to enable caller ID and they don't want to pay to get it done.</div>
<div><br></div><div>On a side note does anyone know where to find out how to look up or calculate the HEX codes for these messages? It took me a while to find 0x01A1.</div><div><br></div><div><br></div><div>Cheers,</div><div>
