Hi,
and welcome to the NethServer community.
It’s a known issue, see also Webtop translations
Is it about this documentation? WebTop groupware — NS8 documentation
To enable the integrations, you need to select the nethvoice instance in the webtop app settings:
I didn’t test but you’ll need to configure it manually. One advantage of NethServer is that the apps are preconfigured to work together so I think it makes sense to have nethvoice and webtop in the same cluster, they could be installed on different nodes.
I can confirm that the fax number isn’t visible, even when editing the contact.
One needs to manually add the fax number to be able to edit, even if a number was entered before.
EDIT:
Thanks @littleboy , you found a bug.
Thanks to @lucag, it’s already filed: Jira
EDIT2:
It’s already fixed and will be coming with the 5.29.X release. Thanks for reporting.
