Hi<br><br>What is the best way to combine multiple SIP providers to achieve<br><br>1) Higher concurrency (for eg. 2 providers with 50 concurrent calling limits could be combined to give a limit of 100) <br>2) Redundancy (use another if one is down)<br>
<br>I have a feeling that this will need some SIP Proxy like OpenSIPS but what could be the architecture ?<br><br>Much thanks!<br><br clear="all">regards,<br>Anita<br><br>
