<div> </div> <div>I am hoping someone has ran into this issue before. I have a Hub and Spoke VoIP network where my cental point is a CCM 4.1(3)sr2 cluster. Off each spoke are 2651XM routers running Cisco Advanced IP Services 12.4(5) IOS for CME 3.3 and VPN support. All CMEs point only to the hub CCM for outside access. I am having the following results with call transferring:</div> <div> </div> <div>Local CME to Local CME: works</div> <div>Local CME to CCM: fails</div> <div>Local CME to Remote CME (CCM Tandem): fails</div> <div> </div> <div>I am able to complete a tandem calls from CME router to CME router via the CME to CCM ISTs. All CME router have local transcoding and use G.729 across the WAN. The CCM ISTs have CCM software MTPs assigned. If we route the calls directly CME to CME via H.323 dial-peers we are able to transfer CME to CME calls. We added the the voice sevrice voip <cr> allow-connections h323 to h323 <cr> supplimentary-service
h450.12. </div> <div> </div> <div>Thanks, </div> <div>PETER CASANAVE</div> <div>3d SIG BDE, Network Engineer</div><p>
