Have CallManagers at central site and an H323 gateway with PRI at remote site. The remote h323 voice gateway is running IOS 12.4-11, <br>on the call manager , I enabled "Allow peer to preserve H323 calls" <br>on the voice gateway, I tried to config <br>
voice service voip<br>h323<br>call preserve <br><br>but under h323, I can't find the call preserve command. then i added "no h225 timeout keepalive" amd then block the ip connectivity between the phone and the callmanager server, the active call terminated shortly. <br>
<br>How can I preserve the active voice call when the WAN link fails?<br><br>Thanks in advance.<br>
