<p>Friends,</p>
<p>I configured routers with for modem passthrough. When my modem dial RAS
number, It starts negotiation with RAS but keep negotiate and not connected.
Means repeat negotiation again and again till timeout. Once it surprisingly
connected but within 30 sec it disconnected. Network Topology below: </p>

<p>Modem pass through is just like Fax passthrough. both
need to run over a G711 codec.</p>
</div>
<div>
<p> </p>
</div>
<div>
<p>config is pretty simple. just add the following
commands:</p>
</div>
<div>
<p> </p>
</div>
<div>
<p>H323 looks like this:</p>
</div>
<div>
<p> voice service voip<br>
h323<br>
modem passthrough nse codec g711ulaw</p>
</div>
<div>
<p> </p>
</div>
<div>
<p>Also make sure you have VAD turned off on the dial peer(s)</p>
</div>
<div>
<p> </p>
</div>
<div>
<p>MGCP looks like this:</p>
</div>
<div>
<p> </p>
</div>
<div>
<p>mgcp modem passthrough voip mode nse</p>

<p style="margin-bottom: 12pt;">Friends,<br>
<br>
I am currently working on voip setup. With the existing tdm network, dialup
users from different sites dial Remote Access Server in central site. When i
will put routers into that network, can users be able to connect again via voip
setup. Topology includes cisco 3800 routers that connect with Ericson MD110 pbx
through E1 (Pri Qsig). Routers are connected point to point through E1. RAS is
non-cisco. <br>
<br>
Existing Topology:<br>
<br>
IP Network ---------RAS------------PBX--------------------------------------------PBX--------------Dialup
User (Modem)<br>
<br>
Topology after voip setup:<br>
<br>
IP Network
---------RAS------------PBX---------Router-----------------------------Router--------PBX--------------Dialup
User (Modem) <br>
<br>
With some study i come to know that there is concept of modem passthrough that
can be used but someone please explain it briefly. And if someone currently
using it, please write down a sample configuration according to my voip
topology. <br>
<br>
Best Regards</p>
