Help for this problem

[thanghc02]

I use cisco 2911 with 4 FXO port and 1 FXS port for my office. My IP phone is CP 3905

I configure for call internal/ external  ok.

But when i change the dialpeer for outgoing PSTN, I not make a call from internal -> PSTN

I debug error and the error message "disconnect cause 11 " or disconnect text cause  17

When i make a call from internal to PSTN: I hear the busy tone. And  I call for my mobile many time but i till hear the busy tone.

I call from PSTN to extension is ok. And call ext to ext is ok. But call from extension to PSTN have a busy tone

Please help me or have solution for solve this problem.

Issue this command on the port you're using

test voice port x/x/x   si-reg-read 29 1

It sounds like the polarity is reversed on that cable.

[MOHIT SINGH]

I checked the logs. you called 0908043018 and I can see outgoing dial peer 2 was matched but for some reason immediately call was disconnected. Could you check whether fxo port is correctly applied in dial peer 2 also share "show run"

If possible provide below debugs for a call again

debug vpm signal

debug voip ccapi inout

Are you sure your PSTN provider support ground start signaing? Generally they support loop start. Can you try using loop start

voice-port

no signal groundStart

signal loopstart

shut

no shut

Thank MOHIT SINGH.

It's ok for outgoing call. But when i set up 2 months ago, i used signal groundstart, it's work fine.
