What are people generally using these days when designing their services, esp. those that require a user to call a DID to access their system, similar to calling card services. There was a time when this used to be 50 to 1 for DIDs, and about 10 to 1 for number of channels bought in SMB with IP-PBX. </span><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><span style='font-family:"Trebuchet MS","sans-serif";color:#663366'>I believe this would have changed today and assuming a service is pretty popular, the ALOCs are longer due to cheaper rates and convenience of calling. Does anyone have any real world numbers they can share? Is 10 to 1 a good ratio to ensure a user practically never gets a "circuits are busy"?</span><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><span style='font-family:"Trebuchet MS","sans-serif";color:#663366'>Thanks in advance</span><o:p></o:p></p></div></div></div></body></html>
