DX 650 Firmware Issue

Hi,

We developed an android application installed on DX650 to monitor and get the calling number that calling this phone.

we used PhoneStateListener class on our application for monitoring purpose

We already tested this application on mobile device and it working fine

We already tested this application on DX 650 with Firmware : sipdx650.10-1-1-78 and it working fine

When we upgrade the firmware to :sipdx650.10-2-5-194, the application can't get the calling number

When we upgrade the firmware to :sipdx650.10-2-5-212 (latest version), the application also can't get the calling number

Can anyone help me on that ?

Not aware of any known reason why there would be problems with this...definitely recommend opening a ticket with DevNet dev support, so the engineers can retrieve trace logs and escalate with engineering as needed: https://developer.cisco.com/site/devnet/support/
