FXS Status

Hi, I have a cisco router 1700 whit 2 fxs installed. In the fxs port 2/1, I have installed a analog phone, from my IP Phone call to the analog phone, and this rings but when I pickup the analog phone the call is finished.

This output is showed when I call from the IP Phone to the Analog phone:

PORT         CODEC    VAD VTSP STATE            VPM STATE
============ ======== === ==================== ======================
2/0           -         - -                                            FXSLS_ONHOOK
2/1           g729r8    y S_SETUP_REQ_PROC      FXSLS_WAIT_OFFHOOK

When I pickup the call from the analogic phone, the show command change to:

PORT         CODEC    VAD VTSP STATE            VPM STATE
============ ======== === ==================== ======================
2/0           -         - -                                            FXSLS_ONHOOK
2/1           -         - -                                            FXSLS_ONHOOK

The configuration is:

voice-port 2/1
station-id name AnalogPhone

station-id name 7810

dial-peer voice 1 pots
destination-pattern 7810
port 2/1

Any suggestion ¿?

The phone cable that connect the FXS interface card to the telephone must have 2 wire. 4 wire cables are problematic.
Have you configured SIP or H.323 dial-peer?
Configure "gw-accounting syslog" on your router and use "terminal monitor" command to see the disconnection cause on a console.

You can debug your call: debug ccsip messages or debug voip ccapi inout (very verbous but more complex).

What is the configuration of incoming dial-peer?
What is the codec configured?

This is my example:

voice-port 2/1
input gain -5
output attenuation 0
no non-linear
no vad
playout-delay nominal 100
playout-delay mode fixed
cptone IT
