Hi all
I am fairly new to Office 365 and I also don't know a lot about SIPso pardon my ignorance.
I am trying to contact staff at another company using Skype For Business but I am unable to.
They don't use Skype for Business but they state they are sip enabled so I should be able to reach them if my company is SIP enabled, they use Lync.
How do I find out if we are SIP enabled or not? I have been through the office 365 admin section for Skype For Business but see no mention of it anywhere.
The option to communicate with other companies is ticked in here and I can communicate with 2 other companies with no issue but they use Skype For Business and not Lync.
Any thoughts on the topic would be appreciated.
Cheers.
We use SIP on our phone system but I am unsure how it translates to Skype For Business.
