Hello

I am trying to develop a website for my dental surgery using odoo website. I have hit some hurdles and am looking for help and not sure if i can do what I am looking for in odoo. 

1. Want to show separate locations on the site with separate contact details - Such that a vistor to the site is able to pick a location close to him and information pertaining to that location is displayed to the person. Is there a way of using subdomains to route traffic to a separate webpage but have data stored on the same database for marketing etc

2. Click to call functionality on the website and responsive site - not sure how it is done in odoo. eg: 07499237350 is show as call now button. when a person clicks on that it uses skype to call or be able to integrate that with VOIP service and in the instance of mobile phone initiate a call after confirmation from the phone's owner

3. Book online appointments for a specific location but have the contact details in a central location for CRM

I am currently using zoho crm and would like something a bit more robust

 thanks for your help
