Question

i searched a lot for the URI syntax of SIP address for group chat in Skype for business,

i found answer only for a individual chat

so i want to is there any syntax for group chat or chat with multiple peoples

also, i tried adding a Distribution list ID, which does't helped,

Please help me with the proper URI syntax to chat with multiple people

Answer 1

Accepts multiple SIP URIs specified inside angle brackets (<>) without any separator.

im:<sip:user1@host><sip:user2@host>
