<html><body><div style="color:#000; background-color:#fff; font-family:arial, helvetica, sans-serif;font-size:10pt"><div>Hi,</div><div> </div><div>I am currently trying to get a Cisco Callmanager 4.1 and an Asterisk server (1.6.2.21) to talk via a SIP trunk so I can use the Voicemail component of the Asterisk (all the phones are associated with the Callmanager).</div><div>The connection seem to be there. When I do a "sip show peers" on the Asterisk server I see the Callmanager as Monitored and online however I can't get any calls to pass from the CM to the Asterisk. If I debug the SIP I get a regular "SIP/2.0 400 Bad Request - 'Malformed/Missing URL'" which is from the Callmanager.</div><div>Can anybody tell me the cause of this message and/or how I can resolve the problem ?</div><div>Any help would be greatly appreciated </div><div> </div><div>Many thanks</div><div> </div><div>Nigel</div></div></body></html>
