Hello, We currently have over 500 extensions, most of them sharing the same profile which has presence enabled (since some of them need shared lines and BLFs). I am now watching the future of having over 6,000 extensions on that PBX. So' I have a few questions: - Does having all the phones on the same profile can induce performance problems which we won't face if we split them among a few profiles? - Is there a difrerence (mainly database access) between placing all phones that need presence on the same profile vs. splitting them to 3-4 profiles? - About 2/3 of the phones do not really need presence; however, it is more comfortable for me to put them on the same profile. Will the databases access due to presence events might be so high that I should invest the effort to put the single line phones on a different profile without presence? Thanks, __Yehavi:
