How i can sing up with restcomm correctly? - restcomm

Question

Already few weeks i try sing up on SIP service with restcomm for android. I check connection with third-party application (cSipSimple) and everything works correctly. But when i try coonection with restcomm demo app, connection falls everytime after 4 seconds. Whats wrong with my sdk or how i can sing up right?
SipProfile sipProfile = new SipProfile();
HashMap<String, Object> params = new HashMap<String, Object>();
params.put("pref_proxy_ip", "my.server.ip");
params.put("pref_proxy_port", "5060");
params.put("pref_sip_user", "7879114");
params.put("pref_sip_password", "EeFei2Fa");
for (String key : params.keySet()) {
if (key.equals("pref_proxy_ip")) {
sipProfile.setRemoteIp((String) params.get(key));
} else if (key.equals("pref_proxy_port")) {
sipProfile.setRemotePort(Integer.parseInt((String) params.get(key)));
} else if (key.equals("pref_sip_user")) {
sipProfile.setSipUserName((String) params.get(key));
} else if (key.equals("pref_sip_password")) {
sipProfile.setSipPassword((String) params.get(key));
}
}
final SipManager sipManager = new SipManager(sipProfile, true);
Register registerRequest = new Register();
final Request r = registerRequest.MakeRequest(sipManager, 100000, null);
// Send the request statefully, through the client transaction.
Thread thread = new Thread() {
public void run() {
try {
final ClientTransaction transaction = sipManager.sipProvider.getNewClientTransaction(r);
transaction.sendRequest();
} catch (SipException e) {
e.printStackTrace();
}
}
};
thread.start();

#Vladislav, you are using the low level facilities of the SDK which are obsolete and not meant to be used directly. I would suggest that you use the RestCommClient API as exposed by the SDK directly. It is much easier to use and provides the same functionality and more.
For an example on how to use it please check:
https://github.com/RestComm/restcomm-android-sdk/blob/master/Examples/restcomm-helloworld/app/src/main/java/com/telestax/restcomm_helloworld/MainActivity.java
You need to change the SIP server settings from:
https://github.com/RestComm/restcomm-android-sdk/blob/master/Examples/restcomm-helloworld/app/src/main/java/com/telestax/restcomm_helloworld/MainActivity.java#L99
And the called party from:
https://github.com/RestComm/restcomm-android-sdk/blob/master/Examples/restcomm-helloworld/app/src/main/java/com/telestax/restcomm_helloworld/MainActivity.java#L174
Just keep in mind that for media Webrtc is used so that NATs can be handled properly. This means that the receiving party needs to be able to handle Webrtc as well. Unless there's a server in the middle handling the mediation, like Restcomm-Connect.
