        <div>However, when I contacted a company called &quot;Matrix Telecom

          SIM support. On asking them to compare the two gateways, they
          said that the one available at ebay is a Chinese gateway about

                            <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>
