After upgrading to firmware version 7.4.7, the SPA-504G phone disconnects the existing call when a speeddial button is pressed. This problem occurs with 7.4.7, 7.4.6, 7.4.4, but does NOT occur in 7.4.3. This problem occurs with both fnc=blf+sd and fnc=sd for the "Extended Function" field. Here's a sample case:
1. Someone calls your phone (extension 200)
2. You want to transfer the call to someone on speeddial (e.g. extension 201)
3. You press the corresponding speed dial button, and wait for the XferLx softkey to appear.
4. Instead, immediately after you press the speed dial button, the call is terminated.
This issue does not occur on a SPA-508G with the same firmware versions (only the SPA-504G). Seems to be either a firmware bug, or an option I've missed.
After updating to Asterisk 1.8.2, this issue seems to be resolved.
