Hi ,
I've discovered that there is a problem with WeSIP looping back to
its own address (which is what you are trying to do). We are fixing
it but it'll take more time. As a workaround you can do thre
different things.
1) Let OpenSER discover the next hop before passing the message to
WeSIP then proxy from WeSIP to the next hop.
<--------- Transaction 1 ---------> <-------- Transaction
2------------>
UAC ---------> [OpenSER --> WeSIP --> OpenSER] ---------> UAS
1.1 UAC sends request with RURI=sip:[EMAIL PROTECTED]
1.2 OpenSER modifies the RURI after consulting the location info
RURI=sip:[EMAIL PROTECTED]
1.3 OpenSER passes the modified message to WeSIP
1.4 WeSIP processes and proxies
1.5 OpenSER processes message coming from WeSIP (if X-WeSIP-SPIRAL
was used) and forwards it downstream
2) Use separated WeSIP with its own OpenSER frontend( see Openser.cfg
working as WeSIP front-end at http://www.wesip.com/mediawiki/
index.php/Configuration#Openser.cfg_in_standalone)
<---Trans 1----><----- Transaction 2 ------><-----Transaction 3------
><---Trans 4--->
UAC ----> OpenSER ----> (WeSIP with OpenSER frontend) ----> OpenSER
------> UAS
2.1 UAC sends request with RURI=sip:[EMAIL PROTECTED]
2.2 OpenSER delivers message to standalone WeSIP
2.3 WeSIP processes and proxies back to OpenSER (WeSIP may
RecordRoute or not)
2.4 OpenSER modifies the RURI after consulting the location info
RURI=sip:[EMAIL PROTECTED]
2.5 OpenSER proxies to UAS
3) Use different IP to make WeSIP think that it is forwarding to
a different host and not looping
<-------Transaction 1--------><------------- Transaction 2
-------------><---Transaction 3---->
UAC ----> [OpenSER --> WeSIP --> OpenSER] ---------> OpenSER
(192.168.1.12) ------> UAS
1.1 UAC sends request with RURI=sip:[EMAIL PROTECTED]
1.2 OpenSER modifies the RURI to an alias IP RURI=sip:
[EMAIL PROTECTED] (192.168.1.12 is a second IP where OpenSER listens)
1.3 OpenSER passes the modified message to WeSIP
1.4 WeSIP processes and proxies to 192.168.1.12 (No loopback failure
since 192.168.1.12 != 192.168.1.11)
1.5 OpenSER processes message coming from WeSIP (if X-WeSIP-SPIRAL
was used) and forwards it to 192.168.1.12
1.6 OpenSER receives proxied message (in IP 192.168.69.12)
1.7 OpenSER applies location translation
1.8 OpenSER forwards
Hope it helps

Hi Gines, thanks for your support
Your servlet named "neo" is being executed and looks like it is
proxying but what from what I see in the packet it is proxying to
itself. Could you try to proxy to another address and see if this
still happens ? Aside, could you send me your configuration files and
your servlet code ?
The serlvet code is the following
protected void doInvite(SipServletRequest callerInvite) throws
ServletException,
IOException {
//Get a proxy for this request
Proxy callerProxy = callerInvite.getProxy();
System.out.println("doInvite within neos servlet: requestURI is " +
callerInvite.getRequestURI() );
callerProxy.proxyTo(callerInvite.getRequestURI());
}
This code causes the "no route" exception. The println above gives :
doInvite within neos servlet: requestURI is sip:[EMAIL PROTECTED]
where 5002 is the called SIP phone and 192.168.1.11 is the address
of my OpenSER
+ WeSIP box (i.e. the managed SIP domain)
Following your advice I have tried to change the proxyTo to a
different address:
SipURI dest = sipFactory.createSipURI("5002","192.168.1.16");
callerProxy.proxyTo(dest);
It that case, the called phone (5002, IP address 192.168.1.16) gets
the INVITE
correctly. However, something puzzles me here: the serlvet is not
supposed to
know the IP address of the called phone. In my understanding, the
AS processes
the INVITE, then it must send it back to the proxy server which is
supposed to
forward it to the next hop, is that right ?
Could you please give me an example of a doInvite which basically
does nothing
and which lets the INVITE be forwarded to the called party ?
Finally here are my config files:
