Created by: Jimmy Liang on 13-07-2010 06:53:41 PM We setup a CMECSTAListener to monitor a phone extension events. However, after received the first "ADDRESS_ACTIVATED" event, all other events has been dropped and the listener onNotification method is never invoked. Got error message: "call is null, not able to construct the topo, drop the event". Anybody knows why? Thanks in advanced. Below is the log output from my console: [2010-07-13 14:49:47,812] INFO com.cisco.cme.cti.siputil.DsSipInviteDialogNonInviteProcessInterfaceImpl Request received [2010-07-13 14:49:47,812] INFO com.cisco.cme.cti.siputil.DsSipInviteDialogNonInviteProcessInterfaceImpl ------------------- request ------------------ [2010-07-13 14:49:47,812] INFO com.cisco.cme.cti.siputil.DsSipInviteDialogNonInviteProcessInterfaceImpl INFO sip:101_0013C3D664D7@192.168.30.166:5060;transport=tcp SIP/2.0 Via: SIP/2.0/TCP 192.168.1.88:5060;branch=z9hG4bK3C661 Max-Forwards: 69 To: CME_SDK <sip:101_0013C3D664D7@csta-sdk>;tag=ds2e9594bb From: <sip:101@192.168.1.88>;tag=446DD8-16BE Call-ID: 12790469607502@192.168.30.166 CSeq: 101 INFO Content-Length: 390 Date: Tue, 13 Jul 2010 18:55:31 GMT User-Agent: Cisco-SIPGateway/IOS-12.x Timestamp: 1279047357 Contact: <sip:101@192.168.1.88:5060;transport=tcp> Content-Type: application/csta+xml Content-Disposition: signal;handling=required

Subject: RE: Event dropped because all object is null, why? Replied by: Yaw-Ming Chen on 13-07-2010 07:57:07 PM Hi, You may need to post your IOS config and codes so can dig into the issue. Thanks !
Subject: RE: Event dropped because all object is null, why? Replied by: Jimmy Liang on 14-07-2010 06:35:52 PM We figured this out. Our incoming calls are from Call Manager, and the CCM talks the CME via H.323 gateway. Once we changed the H.323 gateway to a SIP trunk, it starts working. However, there are still potential issues because we have no control of our customer's CCM settings.
