Hi ,<div> Make ss7 loop back and check the issue(use 2 ss7 server or 2 port card on same server ) .<br><br><div class="gmail_quote">On Wed, Sep 21, 2011 at 3:23 PM, huseyin kalyoncu <span dir="ltr"><<a href="mailto:hkalyoncu@gmail.com">hkalyoncu@gmail.com</a>></span> wrote:<br>

<br>
we have an sangoma AFT104 card installed on asterisk box connected to<br>
alcatel switch via ss7.<br>
we use asterisk box for db lookup; call enters asterisk box then<br>
an agi script performs some db lookups then returns call to alcatel<br>
with a single command like this:<br>
EXEC Dial DAHDI/g1/81B01XXXXXXXXXX<br>
<br>
the problem is chan_dahdi & libss7 cannot send alphanumeric extension<br>
to alcatel.<br>
in alcatel "B01" seen as "001".<br>
is there any way to send alphanumeric extension over ss7 with<br>
chan_dahdi & libss7.<br>
thanks<br>
