Attended Transfer button stops responding

[carel]

Hi,

Asterisk: 1.8.20.0
FreePBX: 2.10.0
FOP: 2.2.27 64bit
OS: Centos 6.4 (64bit)

Issue: From a fresh restart (amportal restart and then fop2 restart), you can normally get one attended transfer to work. After that subsequent attended transfers doesn't work and it looks like the buttons are completely unresponsive. We have a number of external numbers we have buttons configured for to transfer out to, and usually once you click on one of these buttons the Transfer to Voicemail button is greyed out, but when the buttons become unresponsive, this does not get greyed out as normal.

Any ideas on what may be causing this? The logs when running fop2 in debug does not show any command being sent to asterisk other than the regular ping.

Thanks,
Carel

Let me know how do you configure the buttons to transfer out so I can try to replicate the configuration and try it locally.

Hi Nicolas,

Here's one of the buttons which is in buttons.cnf:

[SIP/02031234567]
type=extension
extension=02031234567
context=transfer
label=Test Button
group=GROUPA

Kind Regards,
Carel
