Hi,<br>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.<br>
Do you think it is a good test ? <br>Could i define a little dialplan to test SIP to SS7 and SS7 to SIP ?<br><br></blockquote></div></div><div><br><br>Asterisk (and the rest of softswitches) is free, and cards from Digium (and some competitors) are quite cheap, expensive is carrier-grade telco switch, where the smallest card has a 16 x E1 and costs more that 10 x ( DE410P + HWEC + good quad core 1U server). <br>
<br>TDMoE is your friend. <br>As far as i remember there is no way to have two separate asterisk on one psychical TE410P/TE210P, you need two hosts (two PCs) one of them needs to have a TE410p, another one could use TDMoE or another E100P card or something.<br>
But this setup will work in 100%.<br><br>Better is to check if someone has successfully connected to your-carrier type switch, so if your carrier has a SS7 switch from vendor X in version of Y and you want to pass a services like A,B,C, you should ask if someone had trouble using A,B,C on X in version Y. If it's just simple voice calls with ISUP version 1, then it will work.<br>
