Extension "in use" problem

I have a customer that keeps getting extensions marked as “In Use” when they are not. I have a couple questions;

What causes a line to be marked as “in use”?

Is there a way to reset the line status without restarting the server? I have tried restarting SIP and all the normal tricks but nothing seems to work. I have also had a look in the database and cannot see where the extension is marked as In Use.

Is there a way to set the extensions so that the server periodically looks to ensure the state is correct for the line?

Thanks

Where are you seeing the inuse in asterisk. You have provided no details like FreePBX Version, Asterisk Version, output of your core show hints and core show channels.

If you are referring to queue calls a core show queues would help also. Remember asking questions with no data usually gets no response.

The version the customer is running is FreePBX Distro 1.8.2.0-2.

I’m seeing the in use in the FreePBX “Asterix Info” Module under the headding “Subscribe/Notify”

As per below (Notice Extens 850);

What is the output of ‘core show channels’ and ‘sip show channels’ when SIP/850 shows in use?

Any chance DND is set on the extension? You can check in the ASTDB with database show command.

When I do a database show I see nothing out of normal for extension 850..

Alan - Please notice I updated your post to include the code tags so it can be read now. In the future please format your posts so that are readable.

What kind of device is extension 850? It is clearly hung in a SIP dialog.

You may find this setting gives you some relief, use SIP settings module.

rtptimeout=240

Are you able to do a soft hangup on the channel (tab complete will help fill in the target)?

Thanks for your help SkykingOH, the device type is a YeaLink IP phone (T20).

Regarding the “soft hangup” command, I have not been able to find this command in the FreePBX (Asterisk 1.8) it does not seen to be available either directly from the CLI or under the core command either.

I did find the “channel request hangup”, is this the same as soft hangup?

Also I have extended the RTPtimeout to 240 (from the default 30) what does this do? I would of thought extending the timer would make the problem worse?

Re the formatting, how the heck do you cut and paste of a screen shot into the forum? I’ve been trying to work this out :frowning:

Thanks Again

I just cut and paste from Putty, use the [code][/code] tags to switch to fixed pitch font.

All the bbcodes are documented in the “input format” box below the text entry area.

Yes soft hangup is now channel request hangup

Hi Alan,

I have the same issue you have posted at the top of this thread.
Did you manage to get this solved. If yes, please be kind enough
to post the resolution here. Or any one else please post the way to get
rid of the issue

Thanks in advance

Lohitha

i have a freepbx 2.9.0.12 suddenly one of my extension are saying that ‘personal extension is on the phone’ what can i do to fix this issue?

Stavrosch - Don’t hijack someone else’s post

OP - Extension 580 is in use in your example

what is the solution because i’m trying this command and they are not working.

Thanks
