I am using a Grandstream 2000 and looking to add more. I am hoping, using the "2talk One Number" service I can have multiple sip logins using the -- etc suffix for multiple extensions. This works fine with the soft phone testing I have been trying.
My goal is not to have an exchange in the office but to use 2talk. Am I able to transfer calls from say 123-4567 to 123-4567-1 (ie another phone on the same 2talk one number login)?
