Parked Calls Disconnecting

[pmartin]

Here my issues....Whenever a call comes in and is answered, when the called is then put on hold longer than 2 minutes it just disconnects. Is there a setting somewhere for this? End users are using Ubuntu/Twinkle. Thanks in advance.

Destination for Orphaned Parked Calls:

In the FreePBX Parking Lot screen. Also set the timeout.

I dont think this is the issue just because i do not have the Parking Lot feature enabled. Other suggestions?

 

[pmartin]

Could it possibly be my rtptimeout in the sip_general_custom.conf? Its currently set to rtptimeout=120

 

[pmartin]

Yes..MOH is being used.

End users are using Ubuntu/Twinkle.

Have you tried changing the Call Hold variant field in Twinkle?

A similar problem identified with Bria was solved by setting rtp:inactivity:timer_enabled to 0. Does Twinkle have a rtp inactivity timer?

 

[pmartin]

Not really sure what i should or shouldnt be changing in the call variant field...The RFC value,??? I have no idea if twinkle has a rtp inactivity timer...Anyone?

I set up Twinkle on Ubuntu 10.10 Desktop and was able to reproduce this issue. I had the same test results with X-lite 4 and Windows Vista.

When the far end placed the call on hold the softphone would disconnect after 2 min. When the call was placed on hold at the Twinkle or X-lite end, the call did not disconnect.

Changing rtptimeout=120 to rpttimeout=180, caused the call to disconnect after 3 minutes.

Not sure that is the correct fix, but it does have an affect on how long the call is on hold before it drops.

Additional tests...

I set rpttimeout back to 120 and set rtpkeepalive to 30. The call did not drop until I hung up one of the end points.

The default value for rtpkeepalive is 0. There is also a rtpholdtimeout set to 300, but did not have an affect on the hold time as the call stayed on hold for over 6 mins. before I hung up.

I will try to find out more about rptkeepalive, but for now I am setting mine to value 30.

Thank you so much Ronw...Where do i change the rtpkeepalive value? All i have in my sip_general_custom.conf is the rtptimeout=120. Do i add it here or is this values somewhere else? One more question...Im editing this file through freepbx-tools-config edit, is this fine?

You can make the changes as you are doing, but it is best to go to Tools->Asterisk SIP Settings and make the changes there. It is about the middle of the page under MEDIA & RTP Settings.

It will depend on the version of FreePBX if Asterisk SIP Settings is available.

I have googl'd rtpkeepalive and find many discussions on the topic. Apparantly it is a work around for those devices not sending rtp packets during silence.

 

[pmartin]

Unfortunately its not there...probably cause im still using Freepbx 2.5....I assume it doesnt hurt anything to make the changes the way im doing it, correct?

 

[ronw]

that is correct
