<p class="MsoNormal">Hi,</p>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">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. </p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">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. </p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">I am seeking recommendation on following points:</p>
</div>
<div>
<ol start="1" type="1">
<li class="MsoNormal">Which card should I buy that is most easily configurable with the Freeswitch i.e. company and type. </li><li class="MsoNormal">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>

<p class="MsoNormal">Regards,</p>
