CMS

Guild infrastructure tools (cms, forum, voice chat)?

I ask for advice on what tools to choose to create the infrastructure of the guild. By this I mean four main components:

• A site where information about the guild, news, composition, etc. is published.
  
• Forum where the main communication and coordination of actions takes place.
  
• Voice chat, where people communicate during the game and just like that.
  
• Spreadsheets where various information is entered, for example, DKP or guild property.
  

I'm going to use the Wordpress + Vanilla (or phpBB) combination. It has a lot of advantages, for example, additional plugins for WordPress, for example, chat, export of achievements, various cool features, etc. But there are also disadvantages, in particular, as far as I know, the lack of integration with voice chat without very serious file work with databases.
For voice chat, I'm going to use Mumble. Ventrilo is an expensive solution, and Raidcall does not allow you to install your own server. Perhaps there are other options, I would be grateful if you tell me.
My question is, are there better options for guilds? Perhaps there are cmsks that immediately have all the necessary functions? Or are there simpler options for integrating the right products?
I am considering free, open-source options, but you can also look in the direction of paid products, including services.
