I have an Aastra 57i with side car setup as the phone for the operator. Since I have the side car with BLFs for all the other extensions on the system, every light becomes active as Asterisk calls every SIP device. This in itself is not a big deal, the problem is that as all the devices become active it bogs the phone down and the user is not able to speak until all the BLF notifications have gone through. I know this is not really a problem with Asterisk as much as it is the phone, but my question is: Is there anyway to temporarily disable BLF either through Asterisk or perhaps some SIP command to the phone? Or perhaps another solution?
Thanks for the help,
