Hi Tolga,

Try it in 12.2T IOS image and see if it works? Sounds like you did your
homework very well and are on the right track.

hi peter,

thanks for your help,
at the real s’te there is cisco 2610 and 11.0(5)T1 IOS on it with 4 port
FXO/

today at the firm i tried some configurations to solve the problem, i have a
cisco 3660 test router and FXO ports on this test router with 12.2(11)T. I
wrote the configuration about dial=peers, and then i configured the voice
ports (FXOs) according to cisco documantation. I just wrote these under the
voice port:

voice-port 1/0/0
connection plar 123456
supervisory disconnect anytone

then it is working, there are so many things about FXO disconnect problem at
the cisco web site (i.e. battery reserval,supervisory disconnect
dualtime…, timeouts call and wait disconnect etc ). But it is
working with supervisory disconnect anytonecommand on the cisco 3600.

On the other side, i have to try these FXO ports with cisco 2600 router, so
i got a cisco 2610 test router with sane FXOs, ant there are 48 Mbyes memory
and 16 MB flash on this, i installed the 12.1.(5)17T IOS on this 2600 test
router, because on the cisco web site for supervisory disconnect anytone
command minimum 12.1(3)T and later ISO versions are required. according to
this 12.1.(5)17T IOS satisfies this requirement. I configured dial=peers and
voice port same as previous. then i am looking at the onfiguration with sh
run command i can see same ?

voice-port 1/0/0
connection plar 123456
supervisory disconnect anytone

that is ok but i tried to call the FXO from PSTN same problem occured
although i used supervisory disconnect anytime command

after this, i tried other commands and configurations that cisco web site
recomends. But FXO port release itself 60 secconds later.

I will be crayz, my friends at the firm are teasing me by saying “welcome
the cisco world” :slight_smile:

could you tell me somethings about this problem please?

Hi,

Just off the seat of my pants it seems the FXO isn’t receiving the far =
end
disconnect from the PSTN side thus keeping call up until times out which =
is
set for 65 seconds. You can configure I believe a shorter time out =
period
or upgrade hw/sw to receive the far end disconnect as there are =
different
versions of FXO Vics and you might need FXO-M1 version. I would =
research
this for you on Ciscos website but am very busy today. I would try =
various
search options on www.cisco.com such as far end disconnect, FXO-M1, =
VIC2-FXO
configuration, FXO signaling etc…

yes, there are FXO ports at one side, and FXSs or IVR server at the other
side.
if the caller who is calling from PSTN ends the session the port isnt
released immediately( it released 65 seconds later) on the other end if the
IVR server ends the session everything is ok, FXo port released immediately
you are saying this is becaouse of the analog signalling and there is no
solution?

thanks for youe help!

You can’t have FXO port on both sides of link, you must have on one side FXS
or BRI.and on other side, you can have FXO.
It is normal that if you have FXO on both ends, call never released, this is
analogue signalisation.
