<div dir="ltr">Hi,
<div><br>
</div>
<div>I searched some gateways online. The ones available at ebay
are cheap, the following link shows a gateway supporting 32
SIMS for $859 :</div>
<div><br>
</div>
<div><a href="http://www.ebay.com/itm/GoIP-32-32-Port-VoIP-GSM-Gateway-with-32-External-Antenna-/291811535942" target="_blank">http://www.ebay.com/itm/GoIP-3<wbr>2-32-Port-VoIP-GSM-Gateway-wit<wbr>h-32-External-Antenna-/2918115<wbr>35942</a><br>
</div>
<div><br>
</div>
<div>However, when I contacted a company called "Matrix Telecom
Solution", they gave the quote of $4150 for similar number of
SIM support. On asking them to compare the two gateways, they
said that the one available at ebay is a Chinese gateway about
which they are apprehensive for the quality, warranty and
working.</div>

<div dir="ltr">Hi,
<div><br>
</div>
<div>I am using Freeswitch in an application
that initiates conference calls amongst 20
users in cellular network (mobile phones
in GSM network). Currently, for the
VOIP-GSM gateway, we are using the service
from a company called Doorvaani. </div>
<div><br>
</div>
<div>But, since, the cost of call estimates
to be high and we cannot debug the call
drops; we are thinking to buy our own PRI
card. </div>
<div><br>
</div>
<div>I am seeking recommendation on
following points:</div>
<div>
<ol>
<li>Which card should I buy that is most
easily configurable with the
Freeswitch i.e. company and type. <br>
</li>
<li>Reference on how should I start to
make Freeswitch configure with the PRI
card and start sending and receiving
calls. For the current gateway service
in use, I simply put the
authentication credentials for the
corresponding VOIP line offered by the
company Doorvaani in the external SIP
Profile. In case of PRI, what all
changes are needed?</li>
</ol>
