With great interest I read the post on 3cx integration with the cityline ipdp door phone. http://www.3cx.com/blog/voip-howto/configure-alphatech-ipdp-door-phone/. I was wondering whether the door phone can ring your iphone through the 3xcphone for Iphone software at the moment? Do I need more than just the 3cxphone for Iphone and 3cx software itself? Ie. somewhere I read 3cx only provides the software, not an actual phone number (can you advise how to get that?). Feat requests: 1) Is there any possibility of integrating it with a relay function so you can not only speak to the person at the door but also let them in with a push on a button on your Iphone? 2) Also is there a future plan to make this video based so you can speak / see / allow visitors in all through your iphone? Thanks for letting me know.. not a great IT expert.
