I have a SIP account which I entered into the "Internet Call Settings" of the native android phone app. I am able to place outgoing SIP calls, but no luck with the incoming ones. I am new to the SIP subject, so I was wondering what I am missing and a description how incoming SIP works would be a plus!
- Phone: Nexus 4
- OS: Android 4.3
- SIP Provider: didlogic (sip.didlogic.net)
- Google voice account: available
Feel free to ask for more info. I want to figure this thing out.
EDIT: I am on t-mobile $30 unlimited data and text plan, in case it makes any difference, but it still does not work when im at home on wi-fi.
EDIT 2: Let me ask this: How does the inbound SIP work? Does the phone or wi-fy needs to constantly listen for a signal at the port 5060 or is the phone does a simple alike keep-alive connection with the SIP server in the background?
