Connection to 3CX Phone systems

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Download and setup free 3CX from
http://www.3cx.com/phone-system/downloadlinks.html
2. Connect to the server via Sipdroid, it registers only with TCP (should
register with UDP i belive)
3. Make a call from another phone (Windows based SIP phone from the same
download page works)
4. Make a call to the sipdroid client from the other phone

What is the expected output? What do you see instead?

Voice is delivered when a call is made from the sipdroid client (other end
can hear you but you cannot hear them), nothing is heard either end when
other phone calls sipdroid

What version of the product are you using? On what operating system?

Latest release on HTC Hero running 1.5

Please provide any additional information below.

This maybe a 3CX issue with how they use SIP, but Im sure its due to the
server not reciving RTP packets (the call drops after 30 secs if you call
from the sipdroid client) from the handset.

12:38:54.037  [MS105000] C:41978.1: No RTP packets were
received:remoteAddr=127.0.0.1:40670,extAddr=0.0.0.0:0,localAddr=127.0.0.1:7014

I think thats the cause.. is that the phone blocking the traffic? (maybe orange
locking it down)

I am getting the same issue with G1.  I have tried on both internal network 
loops and
external loops the other phone rings and nothing.  Also I cannot make a call to 
my G1
from the other phone on the network.    I am still going to monkey around with 
3cx to
see if I can make this work.

I am not sure if this has anything to do with it but when I look at my System 
logs on
3cx I notice the ip that is coming from my G1 is not the IP of wireless I am on 
but
the Local-host address the phone is registering as 127.0.0.1:5060.  Even when I 
do
change to TCP It still registers as the local host not the IP it is connecting 
from.
Does this seem right ?

Experimented with this more even when I connect from 3g it registers as
127.0.0.1:5060 so somehow 3cx is not see the true IP of the phone.  I get my G1 
to
work with Trixbox with no issues but with 3cx it is just not registering right.

I was hoping that this issue was going to go away once i updated my phone to the
latest MOD I am using but nope.  Just to let you know I did try also with a 
Un-moded
phone and it did not work either.  Is there a way to force sipdroid to look at 
the
twiland IP or RMNET IP. When I look at what is my IP it lists LO first and then 
other
connections were trixbox just ignores LO it seems 3cx does not and I think that 
is
where we are running into this issue.   I have tried several registration 
tricks like
xxx@xxx.xxx.xx.xxx in both the username field and the server field.  when doing 
that
it does not register at all.  I think the only reason it is registering with 
TCP is
3cx cannot see the other IP of the phone and falls back to having to register 
with
TCP alone.  I Hope to hear back from you all soon.

I have not tested this on 1.18 yet to see if this issue has been resolved or 
not but
I will run it tonight and update accordingly.

I need to reload my 3cx phone system which I will do tonight.    I will comment 
later
tonight if 1.18 fixes this issue.

Any Updates on this issue, I am having the same issue with 3cx server

Original comment by abedfa...@gmail.com on 17 Dec 2009 at 3:03

As far as I can see from pieces of logs -- SipDroid do not provider correct IP
neither in INVITE's Contact header, nor in SDP. In case of INVITE 3CX is still 
able
to answer, because 3CX SIP server sends a reply back to source address (see
rport/received params of Via), and thus to establish SIP session. But in case 
of RTP
such trick doesn't work, because 3CX Media Server believes that 127.0.0.1 is a 
real
destination and sends RTP to it.

Same issue for me as well. It will be great if this can be fixed.

I have a similar problem but not exactly the same. Nonetheless I am posting 
here instead of creating a double :-)

SipDroid 1.5.2 beta HTC Incredible. Phone registers OK with 3CX using either 
UDP or TCP over WLAN or 3G. Stun server selected stun.3cx.com/3478. Problem 
occurs on WLAN behind a NAT router AND on 3G. 

Call from another extension TO the SipDroid extension work FINE (WLAN and 3G). 
Audio is fine, just perfect. 

However, a call FROM SipDroid to another extension does not work: The call 
completes, the other phone rings, and for about 2 seconds I near strange 
squeaking sounds on SipDroid, then SipDroid goes back to the dial screen (with 
the recently used list). Meanwhile, the Call In Progress notification continues 
to appear at the top of the phone, and in the notification pulldown. It never 
goes away. The only thing I can do is kill the SipDroid task.

Perhaps this is related, but in the 3CX admin console, SipDroid shows up 
multiple times with various port numbers, where the other phones are always 
using post 5060, 5061, 5062. The number of listed SIPDroid instances seems to 
vary with usage.

Another possible clue: Ad reported by someone else, I'm getting this in the 
Activity Log:

13:47:19.968  [MS105000] C:1.1: No RTP packets were 
received:remoteAddr=70.167.219.234:21000,extAddr=0.0.0.0:0,localAddr=70.167.219.
233:7000

This was via WLAN with the Wireless router's WAN IP 70.167.219.234 and the 3CX 
running on the machine at 70.167.219.233.

OK I got this working with SipDroid 1.5.2 (beta) and the 3CX V8 PABX/Proxy. 
I've tested with the phone/SipDroid behind a WiFi router connected to our 
public LAN (must NAT to get to the 3CX PABX), and via 3G.

The solution is in 3CX extension config: Turn off Supports Re-Invite on the 
assigned extension (Edit Extension-Ext.xxx, Other tab, Extension Capabilities 
section. I am no VoIP expert; I don't know WHY this works, but it does. 

It is also necessary to use a STUN server.

The problem of SipDroid showing up multiple times on different ports is still 
there (see my prev message) but it seems harmless.

Oh, I should mention that the above was done using UDP for both WiFi/NAT and 3G.
