<p>Thanks for the reply, but unfortunately, I dont think that is correct.</p>

<h3 class="p_H_Head3">Blocking Two-stage Dialing Service on Analog and Digital FXO Ports
</h3>
<a name="wp1068968"></a>
<p class="pB1_Body1">Cisco Unified CME 8.1 and later versions block the two-stage dialing service which is initiated when an Analog or Digital FXO port goes offhook and the private line automatic ringdown (PLAR) connection is not setup from the voice-port.
As a result, no outbound dial-peer is selected for an incoming analog or digital FXO call and no dialed digits are collected from an FXO call. Cisco Unified CME and voice gateways disconnect the FXO call with cause-code "unassigned-number (1)". Cisco Unified CME
uses the<span style="FONT-STYLE: normal; COLOR: black; FONT-WEIGHT: bold"> no secondary dialtone</span> command by default from FXO voice-port to block the two-stage dialing service on Analog or digital FXO ports.</p>

<div style="FONT-FAMILY: Times New Roman; COLOR: #000000; FONT-SIZE: 16px">This implies that if I do not configure connection plar on the FXO port, I should get secondary dialtone. This is what I always thought to be true.</div>

<div style="FONT-FAMILY: Times New Roman; COLOR: #000000; FONT-SIZE: 16px">This document did, however, lead me to discover that the "no secondary dialtone" command was on by default on the FXO port. I reversed the command, but still no secondary dial-tone.</div>

<div>For calls inbound to FXO ports, you would need to configure connection plar.<br>

<p>Scenario: Using a 2811 router as a PSTN emulator. Has a 2 port FXS card installed. One port has an analog phone attached, other port is connected to a 4 port FXO card installed into a 2951 router. 2951 is H323 with CUCM 8.6. Simple/test dial peers configured.

<p>I have other dial-peers on this router (not shown) that will take the inbound digits. However, Im never able to pass the digits.</p>
<p style="PADDING-BOTTOM: 0px; MIN-HEIGHT: 8pt; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; PADDING-TOP: 0px">
</p>
<p>Calls from the VoIP network to the simulated PSTN work fine. Calls from the PSTN to the VoIP network fail.
</p>
<p style="PADDING-BOTTOM: 0px; MIN-HEIGHT: 8pt; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; PADDING-TOP: 0px">
</p>
<p>When I pick up the analog phone, I get the expected dial tone. I enter "9999" and the call rings to the FXS port and I hear the FXO port answer. I get the expected secondary (2 stage) dial tone, but then before I can press any digits, the FXo port hangs
up and I am left with the PSTN router dial tone.</p>
<p style="PADDING-BOTTOM: 0px; MIN-HEIGHT: 8pt; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; PADDING-TOP: 0px">

<p>debug voip dialpeer on the H323 router shows no results at all when I try to place the call.</p>
<p>debug voip dialpeer on the PSTN router shows the expected dial peer matching and the expected result. File is attached.</p>
<p style="PADDING-BOTTOM: 0px; MIN-HEIGHT: 8pt; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; PADDING-TOP: 0px">
</p>
<p>Additionally, when I observe the output of show voice port summary while I place the call, I see the FXS port (the one that is tied to the FXO port) go off hook and then go back on hook (file also attached)</p>
<p style="PADDING-BOTTOM: 0px; MIN-HEIGHT: 8pt; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; PADDING-TOP: 0px">
</p>
<p>So, the FXO port appears to be looking for something from the FXS when it answers the call, doesnt get it (or doesnt like what it gets) so it hangs up.</p>
<p style="PADDING-BOTTOM: 0px; MIN-HEIGHT: 8pt; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; PADDING-TOP: 0px">

<p>Looking for help...</p>
