Hi, Don't know if it's the good place to post this, but In order to provision multiple handsets on a Yealink W52P, I modify the original template. You can find it as attachment. The template must be assign to one main extension account. Other extension are secondary, without template assigned. Secondary extension are declared in BLF fields, in the main extension. Order is important, and start at BLF number 2 (the first BLF field is not used) Because of limited BLF parameter in template, it's not usable for all of you (security concern), but it could... * Password for secondary extension must be the same as the main one, adding BLF number position as suffix. ("<main pwd>2" for extension number 2). (suffix can be modified in the template) * SIP ID, ID, and extension number must be the same. (existing %%<BLF parameters>%% are limited in template) If you have this need, and wish 3CX works on a better method for future release, you should vote for that 3CX idea ;-) https://apps.facebook.com/threecxideas/index.php?page=idea_detail.php&i=876 Dont hesitate to share your modifications.
