I have a landline and Internet at home. I have internet and a mobile phone at job. I want to use my landline as phone line for my mobile phone though internet. Exemple, when i get a call on my landline the call is send to internet to my mobile phone. My mobile phone ring. When i talk to my mobile phone, it's "talk" to my landline at home... Is clear? :S Exemple, when i do a call to my mobile phone, it's in realty do a call from my landline. Do you understand a little bit what i want? Why? The goal? To use only a data plan on my mobile phone, also do get a call from a local number (my landline), also do do a local call from every where i have Wifi, internet... Is it possible with 3CX and Cisco SPA3102 ? Thank you!!
