<p class="MsoNormal"><a name="secondary">This step is necessary because by default, the H.225 timer that controls redirection to a less preferred dial peer on a "no-response" failure is longer than the ten second timer of the Q.931 Call Proceeding timer. When
a call comes in to an H.323 gateway through an ISDN trunk and gets forwarded to an inoperative Cisco CallManager, the router waits for forty seconds before it attempts to use a dial peer with a lower preference, or before it clears the call. By the time this
occurs, the ISDN Q.931 that signals on the H.323 gateway has already sent an ISDN Q.931 CALL DISCONNECT to the ISDN switch. The router provides an ISDN clearing code of 0x8066—"recovery on timer expiry."</a><o:p></o:p></p>
<p class="MsoNormal">It is not possible for the H.323 gateway to reset the Call Proceeding timer because it attempts to use a different dial-peer. Therefore, the H.323 gateway must switch peers and complete the call with the help of the secondary Cisco CallManager
server within the ten seconds allowed by the Q.931 (Incoming Call Proceeding) timer.<o:p></o:p></p>
<p class="MsoNormal">When the H.225 timer is set to three seconds, the router attempts a connection to the primary Cisco CallManager server. If it does not receive a response in three seconds, it falls back to the secondary Cisco CallManager server.<o:p></o:p></p>

<p class="MsoNormal"><span lang="EN-IE" style="font-size:10.0pt;font-family:"Verdana","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-IE" style="font-size:10.0pt;font-family:"Verdana","sans-serif"">I posted about this while back but I thought it was an isolated incident relating to the provider.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-IE" style="font-size:10.0pt;font-family:"Verdana","sans-serif"">Basically, from an external phone, if I dial a DDI number that doesn’t have an extension set up in call manager, I hear ringback for about 20 seconds before
I get the busy/disconnect tone. As I said, I thought this was an isolated incident on one particular site relating to a BRI but tests have show it actual happens on another site (same CM cluster) for a PRI.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-IE" style="font-size:10.0pt;font-family:"Verdana","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-IE" style="font-size:10.0pt;font-family:"Verdana","sans-serif"">I’m guessing this is might be a H323 signalling issue (all gateways are H323) or Call Manager issue but I don’t know what to even look for.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-IE" style="font-size:10.0pt;font-family:"Verdana","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-IE" style="font-size:10.0pt;font-family:"Verdana","sans-serif"">Any help would be appreciated. I will be logging a TAC case for it but I thought I’d post anyway in case it’s a known (obviously not to me) issue.<o:p></o:p></span></p>
