- A new way of doing BLF pickup was introduced into 1.6.2. This feature
adds a
- call-id value into the XML of a SIP_NOTIFY message sent to alert a
subscriber
- that a device is ringing. This option should only be enabled when the
new
- 'notifycid' option is set, but this was not the case. Instead
the call-id
- value was included for every RINGING Notify message, which caused a
- regression for people who used other methods for call pickup.
- (Closes issue #17633. Reported, patched by urosh. Patched by dvossel.
- Tested by: dvossel, urosh, okrief, alecdavis)
