<div dir="ltr">Hi,<br><br><br>As I understand, libss7 implements MTP and ISUP protocols over DAHDI compatible hardware.<br><br><br>I need to establish a call from Asterisk to a GSM subscriber by initiating a call directly over the GMSC or STP that connects to MSC of the subscriber. Here, I suppose that Asterisk acts as a VMSC in the telco carrier of the subscriber.<br>
<br><br>For signaling part of the call, I suppose that MAP protocol will be used first to get some information about the subscriber and then ISUP will be used to initiate the call.<br><br><br>For voice part, DAHDI hardware will be used to carry the data.<br>
<br><br>My questions are:<br><br> 1- Are the information above correct?<br> 2- Can libss7 be used for ISUP and voice part of my project?<br> 3- Is there any information regarding connecting Asterisk to a GMSC or STP?<br>
<br><br>Please help.<br><br>--<br>BR<br>Abdelkader Mosbah.<br></div>
