<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am using chan_ss7 1.0.0 with success, where I
pass SIP calls to SS7 switch, however I am facing a nagging problem that
prevents the deployment in a production environment.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am using asterisk 1.2.24</FONT></DIV>
<DIV><FONT face=Arial size=2>Zaptel 1.2.20.1</FONT></DIV>
<DIV><FONT face=Arial size=2>Chan_ss7 1.0.0</FONT></DIV>
<DIV><FONT face=Arial size=2>Digium TE410P</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>When I connect asterisk to the SS7 switch eveything
works fine for sometime, then I start loosing channels (CICs) on the 4 active
E1s, and by time I get the following messages:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>WARNING[22344] l4isup.c: No idle circuit
found.<BR>WARNING[22344] l4isup.c: SS7 requester: No idle circuit
available.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>By time I get all my CICs unusable </FONT><FONT
face=Arial size=2>although "ss7 show channels" shows many channels as
"idle"</FONT></DIV>
<DIV><FONT face=Arial size=2>(I had the same problme with both chan_ss7 0.9, and
the pl patched version of it)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Now using chan_ss7 1.0.0 and issuing "ss7s status"
I get something like this:</FONT></DIV>
<DIV><FONT face=Arial size=2>C7-server*CLI> ss7
status<BR>linkset idle busy initiating
resetting total incoming total
outgoing<BR>MSC1
36 15

initiating resetting total incoming total
outgoing<BR>MSC2
33 16
11
0
0 4285<BR>*** Idle
list lenth is: 22<BR></FONT></DIV>
<DIV><FONT face=Arial size=2>You can notice that the "idle" channels are more
than the "Idle list length" for both linksets.</FONT></DIV>
<DIV><FONT face=Arial size=2>And when the "*** Idle list length" reaches 0 (but
the linkset has many idle channels) I start getting the "No idle circuit
found" message and calls fail, and of course I only have like 30-40 active ss7
calls on the 120 channels of the 4 E1s.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Your help is much appreciated,</FONT></DIV>
