FXO disconnecting incomming call.

Hi

I have a gateway tjat has a FXO port who has some problems. Outgoing calls works properly, but incoming calls ring on phone in CUCM but when I answer the call is disconnect.

This is my config

Take a H323/SIP debug as well to see what is happening on the IP leg. I don't see this as an issue on the FXO side.

[R0g22 · Accepted solution]

It's the gateway sending the BYE. I looked more closely at the analog logs you added before and I see the following -

*/ Telco does a battery reversal answer supervision -
009793: Apr 10 23:12:30.141: htsp_process_event: [0/1/1, FXOLS_CONNECT, E_DSP_SIG_0110]fxols_rvs_battery

*/ The polarity is reversed again back to normal which is seen as a disconnect by the IOS -
009797: Apr 10 23:12:30.377: htsp_process_event: [0/1/1, FXOLS_CONNECT, E_DSP_SIG_0100]fxols_normal_battery

*/ IOS confirms the disconnect -
009798: Apr 10 23:12:30.377: htsp_timer_stop2 fxols_disc_confirm

Talk to your Telco on this.

Hi

I applied  no battery-reversal on voice-port and every goes ok.

voice-port 0/1/0
 no battery-reversal
 connection plar opx 8100

Thank so much.
