<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When a VOIP user dials an external number, the calls are
routed through our SIP provider. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is there a simple way to check whether the DDI exists
locally before dialling out to the sip provider?<o:p></o:p></p>
<p class=MsoNormal>Something like GotoIfExists(5551234@incoming_calls)<o:p></o:p></p>
<p class=MsoNormal>Currently, I'm paying for all calls, regardless of whether
they exist locally.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>All DDIs exist in the incoming_calls context.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks<o:p></o:p></p>
<p class=MsoNormal>Dan<o:p></o:p></p>
