[OpenSIPStack] OpenSBC simple call scenario not working

[Dana J. <dj...@cs...>]

Hi,

I am new to openSBC and trying to familiarize myself with it.  I am trying 
to get a simple call scenario to work using openSBC but for some reason it 
is not working.  I am using two polycom (PVX) video clients and openSBC 
(installed on CentOS VM):

The scenario is as follows : 

Polycom PVX1 (10.2.10.2) => openSBC (10.2.10.4) => Polycom PVX2 
(10.2.10.13)
 
I am using simple IP addressing for routing the call through openSBC, 
without (Registration).  So for example Polycom PVX1 is 
+17034565000@10.2.10.2, Polycom PVX2 is john@10.2.10.13, and openSBC is 
10.2.10.4 (port 5060)

Both video clients are set to send calls via proxy ...10.2.10.4:5060 and 
this the openSBC..

PVX1's originating URI is entered in the openSBC's (Local-domain-accounts) 
tab (sip:+17034565000@10.2.10.2:5060),  and PVX2's destination routing 
info is entered in the (B2BUA Routes) tab (  [sip:john] sip: 
10.2.10.13:5060  ). 

I have openSBC on B2BUA mode (since I want to take advantage of B2BUA 
functionalities not proxy functionalities).

I have also set the (SIP Transport) tab => main interface (blank), 
therefore it should default to using port 5060.

(Trusted Domains) => Accept all calls (checked).

When I make the calls I see on wireshark the following  message:

source                  destination                     Protocol Info.
10.2.10.2 (PVX1)                10.2.10.4 (openSBC)             SIP/SDP 
INVITE sip:john@10.2.10.2 with session description

10.2.10.4               10.2.10.2                       ICMP Destination 
Unreachable (Host Administravly Prohibited)


Also, when trying to find the detailed logs (PTRACE) logs, which I have 
set to level 5 for detailed logging, I cannot seem to find them.  I am not 
sure if they are being saved with a (ptrace) tag or something else, or 
even if they are being generated at all.  I tried to follow the openSBC 
tab instructions by looking where PWLIB and OPAL libraries , but nothing 
found.

Your feedback in these simple two questions is highly appreciated.

Thanks
