SRV records - service records used in Office 365 - can be added via our DNS Management interface inside the control panel.
If the domain is registered with us, you can get to this from the 'Manage Domains' area of the control panel. If the domain is not with us but is assigned to a hosting package, you can reach this interface via the Manage Hosting -> Choose Package -> Manage DNS section.
Towards the bottom of the Manage DNS page you will see 3 inputs to allow you to add new records. To add one:
- Choose SRV from the Type dropdown.
- In the Name field, type: _sip._tls
- In the Data field, type: sipdir.online.lync.com
- Enter 100 for Priority.
- Enter 1 for Weight.
- Enter 443 as the Port.
For the second record, Click to add another record. A new row will appear.
- Choose SRV from the Type dropdown.
- In the Name field, type: _sipfederationtls._tcp
- In the Data field, type: sipfed.online.lync.com
- Enter 100 for Priority.
- Enter 1 for Weight.
- Enter 5061 as the Port.
Remember to save the records by clicking 'Update DNS'.
That's it!
Your SRV records are now added. Our nameservers will start answering with them almost instantly - but may take up to 2 minutes. If you're running through the Microsoft setup wizard or DNS checker you will be able to continue shortly.
The above SRV records are correct as of 26th February 2017, but we recommend checking your Microsoft account for any changes.
