Avaya CM and CUCM 8.6 BLF

Has anyone come across a configuration guide to get busy lamp fields working between an Avaya CM/SES and CUCM 8.6? We are using a SIP trunk right now and call routing is working great. We just need to get BLF's working between the two systems. I'll take any help I can get.

Hi Chris,

I havent seen BLF working between CUCM and Avaya.

Below is the link which shows all the tested 3rd party deployment and most of them do not show BLF feature between CUCM and Avaya.

Agreed - it generally doesn't work between systems as it's pretty much always implemeneted in a proprietary way.

We would always advise clients to migrate users that have close working relationships that require BLFs, shared lines, pickup groups etc as a unit to the same phone system. If that's not practical then they'll just have to accept the limitations of being on separate systems.

+5 to Aaron.

Customer must be educated that integrating phone systems is not like decorating an house with different pieces of furniture.
