i have a garage opener which only communicates thru SIP INFO. when I call viop clients bria they are able to open the door .. but the connection on 3G/4G/wifi isn't stable. so I added a viop provider and thought I would be able to forward the call to my mobile phone when there is no connection with the mobile clients bria/3g/4g/wifi. it works very good I get a call on my mobile phone.. but I can not open the garage because its not recognizing my SIP INFO. my viop provider only supports in-band.. is there a way I can convert a signal from my mobile phone to SIP INFO so my door recognizes it so it will open ?
