<div>Hi Alex,</div>
<div> </div>
<div>I know what you are saying, but the thing is I still want to know what SS7 is about and when would someone needs to do something with it. It makes me uncomfortable to having such a missing link fully understood. </div>
<div> </div>
<div>I would appreciate if you can tell me more about the real SS7. Under what situation would SS7 become a topic that needs to be attended to in an Asterisk implementation?</div>
<div> </div>
<div>Thanks,</div>
<div>Mark<br><br></div>

<div>
<p><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt">I have read about SS7 recently and learnt that it is a signalling protocol used in PSTN for call management, setup, etc. The thing that I don't understand is how SS7 plays a role in VOIP. When I make calls between landline and Asterisk via PSTN, I don't need to do anything with SS7. Is it because the SS7 signalling is already done by Asterisk already? From the prespective of implementing Asterisk, what kind of SS7 support is needed? Is SS7 something needs to be concerned about when using Asterisk with T1/E1?</span></font></p>
