Hi, because E1 cards are quite expensive, and before connecting to PSTN, i would like to test good working of asterisk + libss7 by looping back 2 E1 ports of the same PCI Card (for example : one TE410P). I will connect two SIP phones for test purposes. Do you think it is a good test ? Could i define a little dialplan to test SIP to SS7 and SS7 to SIP ? Thanks, Jean-Louis. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.digium.com/pipermail/asterisk-ss7/attachments/20110426/518c29fb/attachment.htm>
