Hello,

Sorry, but it is impossible to remove the already activated license from the site (it is strictly defined with the licensing protection system). You can only expand the license (on the site, in your account)

What are the problems, describe in more detail. I gave you a link to the documentation, the configuration process is written there in detail.

You can use any SIP server (3CX, Asterisk, PBX etc)

We have some guide https://dev.iridi.com/SIP-telephony/en#Setting_up_of_the_SIP_server

Hello

To work with SIPserver is required (it can be built into the intercom server). We do not support the P2P mode when there are only 2 devices on the network (calling and receiving panel)

There are no pictures in the server project, so it loads quickly enough!

This tool does not compress the project, but removes unused instances of images. Try to make a copy of the project and use this tool - what result will you get? A project is a set of files: textual for all elements, images and scripts. Usually, images occupy the most space, with them and it makes sense to work - there cannot be magic tools in principle )))

It is not so big project ))

Check images in this project, maybe you have a lot unused pictures

How big is your project ???

1. Check that there are no unnecessary pictures in the gallery.

2. Think about the division of the project into several parts (for example, for the owner of the house, for children) ... Split by use model.

Hello

This is available only for the popup, after one version we plan to release this effect for the page.
