Using CSipSimple With OBi

<< < (15/17) > >>

Hi again

I modified my SP1 route
my SP1 X_Inbound Call Route is

{pp(ob290367476),ph},{(Mcot)>(Msp1),(Mcot)>(<**1:>(Msp1)):sp1},{(Mcot)>(<**2:>(Msp2)):sp2},{(Mcot)>(<**8:>(Mli)):li},{(Mcot)>(<**9:>(Mpp)):pp},{(Mcot)>**0:aa},{(Mcot)>0:ph}

with this I get the following history

Call 1   09/15/2013    20:30:57   

Terminal ID   SP2   GoogleVoice1
Peer Name   Mariatweidner   
Peer Number   maria   7145613070
Direction         Inbound   Outbound
20:30:57   Ringing   
20:31:06   End Call

It looks as if the call goes to GoogleVoice, but ... the CSIp client does not ring and the call times out without ringing at the other side. I am at the ppoint where I started last week. The call seem to go to GV but things do not work.

YES!!! Problem solved. Things with CsipSimple work great

Thanks especially to ianobi and to azrobert for their ideas and help. This has to be the simplest way to make Csip work if you have admin access to the router in your LAN


The quality of the call both with WIFI and Data is perfect

the solution works as follows

1. In the router forward all the required ports at the WAN to the OBI inside the LAN

   1   OBI   5060 ~ 5062   5060 ~ 5062   UDP   192.168.1.11   
   2   OBI-1   10000 ~ 11000   10000 ~ 11000   UDP   192.168.1.11   
   3   OBI-2   16600 ~ 16998   16600 ~ 16998   UDP   192.168.1.11   
   4   OBI-3   19305   19305   UDP   192.168.1.11   
   5   OBI-4   5222 ~ 5223   5222 ~ 5223   TCP   192.168.1.11   
   6   OBI-5   6800   6800   TCP/UDP   192.168.1.11
   
2. SP2 X_InboundCallRoute
{('pgonzalezg'):a},{('maria'):sp1)} ,{ph}

3. SP1 X_InboundCallRoute
{pp(ob290367476),ph},{(Mcot)>(Msp1),(Mcot)>(<**1:>(Msp1)):sp1},{(Mcot)>(<**2:>(Msp2)):sp2},{(Mcot)>(<**8:>(Mli)):li},{(Mcot)>(<**9:>(Mpp)):pp},{(Mcot)>**0:aa},{('luis'):sp1},{(Mcot)>0:ph}

The SP2 has a SIP service associated with it to receive calls

The settings at the CSIP client have been explained in this same thread by azrobert.

Further notes on CSIP battery usage
CSIP uses by defaul UDP transport. With this setting and always on (to receive calls) the program was using battery in my Jiayu GS2 (3000 mWh battery) at a pace of over 8% per hour.
I changed the setting "Transport" to TCP in the Account-Edit. This reduced the usage to below 3% per hour.
The quality of the calls is perfect with UDP or TCP, both over WIFI or Data.
Good luck

A MUCH BETTER SOLUTION !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Easier Too ! This is so simple a baby can do this.

Ok. I tried and tried and tried to use the ObiTALK Android app and it SUCKS! (Apple app work ok). So, here is the good news!

I have an OBi100:

- SP1 = GoogleVoice
- SP2 = Callcentric SIP (100% FREE! Free callcentric number and FREE USA DID)
- Auto Attendant turned ON with default values

OBJECTIVE: If specific callcentric users OR anyone (your choice) calls our callcentric number which comes in on SP2 they get our Auto Attendant and can make a free USA phone call.
 
SOLUTION:
IF you put under Voice Services, SP2 Service, X_InboundCallRoute={1777xxxxxxx|1777xxxxxxx>:aa},{ph}    THEN the specified 1777xxxxxxx number/s goes to AA and your DONE !!!!! All other calls rings our phone. AA takes over and completes the call as desired. OBiTALK NOT USED OR ENABLED. OBi services on their web site NOT USED. EVERYTHING CONTROLLED BY YOUR OBi device.

Using cSIPsimple app works PERFECTLY on ALL Android and Apple devices. THE CALLS ARE ALWAYS 100% FREE. No DID number needed. Anyone in the entire world can call your OBi device and make free USA phone calls.

GREAT STUFF !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 

PS. Other SIP apps like Media5 phone (use to be my favorite but no more) and 3CX and many others have serious problems (especially the android apps). The call completes and voice works but is disconnected after a few seconds. MUST USE cSIPsimple !

I really want to try this method but have reservations from a security perspective as far as inbound dialing from Csipsimple to the Obi.  

If I am reading this thread (and several of the others) correctly - and I have read them over and over again - the only security with the sip to sip (not to be confused with sip2sip) connection is by the userid that is passed through the LAN or internet connection to the listening port on the Obi box.  In other words, the Csipsimple app establishes a connection with your routers public IP address which uses the open port (5060 or whatever corresponds to the appropriate Spx you are communicating with) to act as a pass through to the Obi box.  Once this connection is established, your Obi box checks the userid of the inbound communication stream and if it matches,  permits access to the specific Spx for you to make your call through the Obi box to other trunks.

My security concern is if someone else tried to make the same connection to your Obi box using the same sip to sip method, could they make calls through your Obi box if they used the same userid that you had established?  Also, is this method vulnerable to port scanning and other malicious hacking exploits?

If the security possible by the sip to sip connection is too weak, are there any merits to putting the Obi box behind a VPN?  I have read elsewhere of others using Android's built in VPN client to establish connections to a VOIP provider or server.

I am hoping other more knowledgeable forum members can share their thoughts on this subject.
