<div>I'm currently looking to interconnect my Asterisk PBX system with the PSTN via a digital PRI/T1.</div>
<div>I know a multitude of options exist for internal PCI cards (Digium/Sangoma/Rhino), I was wondering if anyone has any experience or recommendations of external PRI media gateways that support SIP.</div>
<div> </div>
<div>So far I've found:</div>
<div>VegaStream Vega 400</div>
<div>Audiocodes Mediant 2000</div>
<div>MediaTrix 1531</div>
<div> </div>
<div>However they are all expensive (over 3,000).</div>
<div> </div>
<div>Does any one have any other suggestions or experience with the above products?</div>
<div> </div>
<div>Thanks,</div>
<div>Jameson</div>
