Possible Change on Transfer to Parking?

Asterisk Asterisk Support
1

We are running Asterisk from RPMs on CentOS 5.5 x64. Currently running Asterisk 1.6.2.17.2.
Our attendant phone is a Linksys SPA 962 with two 932 sidecars. One of the sidecar buttons is set as a speed dial to 700 for call parking (fnc=sd;sub=700@pbxserver)

Under Asterisk 1.6.2.15 when the attendant would answer a call and press the key button for call parking it would park the call and playback the parking lot number to the attendant.

Once we upgraded to 1.6.2.17 it now transfers the call to parking, ends the call to the attendant yet in the log show it doing a playback of the parking lot number but no one hears this.

Example of using the line key to transfer call to parking.

If they use the #700 extension it will playback the parking lot number as it should but the attendants don’t like having to press the extra buttons when they have always simply pressed the Call Park button on the line car.
Example of the #700:

    -- Accepting call from 'xxxxxxxxxx' to 'yyyyyyyyyy' on channel 0/2, span 1

The difference I see is after the line:

On the side car button we get:

While on the #700 it goes right to the call parking and playback.

Anyone else experience this? And how do we get the old functionality back where the attendant can transfer a call using the side car button and still get the playback of the parking lot number?

I am still seeing this on my SPA942 phones. Any resolution or workaround? Seems like no one cares to fix this problem… Ideas?

The ZOMBIE line is the result of using general case transfer code. I think that the features case is treated as a special case, even though you didn’t use the specific parking code.

Having verbose logging on would have helped, but the digits appear to be being announced to the original channel, and the transfer has been done on that channel. That means the phone is doing a blind transfer, and all phones of which I’m aware stop listening to the audio on the original channel immediately after sending the SIP REFER. If you want to hear it on the phone, you must do an attended transfer. In that case, you will see different instance ID’s for the incoming call and for the call to 700, because the phone will set up a new call to 700 and the tell Asterisk to connect the new and old calls when you complete the transfer.

Although this doesn’t seem to be a bug, no-one will fix problems in 1.6.x versions, unless they relate to security. If you want a version that is being actively fixed, you need 1.8.x.

This is a peer support forum, not a bug reporting channel.

There are no service level commitments for the open source version of Asterisk. If you want any guarantee of support or quick fixes, you need to buy a commercially supported version.

You may want to note that a large batch of bug fixes to parking have been previewed for 1.8.5+, just this week.
