Hi,
I have 186x series router with build-in four FXS ports. When I call FXS port (SCCP IP Phone through H.323), I get connected to GSM GW; when I disconnect by IPPhone the line is still busy
Config:
!
voice-port 0/0/3
no supervisory disconnect lcfo
no battery-reversal
signal groundStart
input gain 6
compand-type a-law
no comfort-noise
cptone PL
!
!
dial-peer voice 600 pots
max-conn 1
destination-pattern 0048.........
port 0/0/3
forward-digits all
!
Ani ideas how to say to GSM GW that call is cleared?
Best Regards

To begin with, should be signal loopstart.
Then check GSM box documentation for what disconnect supervision method it can use.
Note these connection are better done with ISDN BRI or SIP. Analog is always source of trouble.

I tried loopstart earlier and the problem still exists
It's a Nokia GSM adapter - the default rule for disconnect supervision in this adapter is monotoring silence. Any idea how to apply such settings on Cisco router ?

Silence is silence, no special config is required.
I have a client with old Nokia adapters and they work acceptably. They are of the type with both FXS and FXO ports.

It is old Nokia adapter - can You paste part of config ? (I'm interested in voice-port part) Thanks
