BLA in Aserisk

Dear sirs,

Does Asterisk support BLA/SLA (Bridged Line Appearance/Shared Line Appearance)?

If yes, which IP phone can work well with Asterisk in BLA? Yealink, Cisco, Avaya, or others?

Thanks for all your answers.

Nobody know about the BLA function?

If anyone know that, please tell me and answer my question. Thank you very much.
