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 ¿?

Re: FXS Status

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.

May  2 14:10:16: %VOIPAAA-5-VOIP_CALL_HISTORY: CallLegType 1, ConnectionId 6AF6A77D 551A11DF 8D5E000E D7B96E74, SetupTime 14:09:39.652 METDST Sun May 2 2010, PeerAddress 3392864698, PeerSubAddress , DisconnectCause 1F  , DisconnectText normal, unspecified (31), ConnectTime 14:10:07.652 METDST Sun May 2 2010, DisconnectTime 14:10:16.576 METDST Sun May 2 2010, CallOrigin 2, ChargedUnits 0, InfoType 2, TransmitPackets 442, TransmitBytes 70564, ReceivePackets 444, ReceiveBytes 70572

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
description *****

dial-peer voice 15 pots

huntstop
destination-pattern 203

dial-peer voice 1 voip

incoming called-number .
modem passthrough nse codec g711alaw
voice-class codec 10
fax protocol pass-through g711alaw
