Hi all,
I'm trying to make two pjsua v0.9.0 applications inter-communicate using a proxy.
My configuration is:
PJSUA_1 : --ip-addr=127.0.0.100 --local-port=6000 --null-audio --proxy=sip:127.0.0.10
PJSUA_2 : --ip-addr=127.0.0.200 --local-port=7000 --null-audio
Proxy (127.0.0.10:5060) is OpenSIPS v1.4.2 with default configuration file.
All calls are originated by PJSUA_1.
1. With the above parameters the two SIP UAs communicate directly. PJSUA_1 does not
transmit the INVITE request to the proxy, but to PJSUA_2. Is that correct behaviour?
2. Adding outbound proxy parameter does not help:
PJSUA_1 : --ip-addr=127.0.0.100 --local-port=6000 --null-audio --proxy=sip:127.0.0.10 \
--outbound=sip:127.0.0.10
PJSUA_2 : --ip-addr=127.0.0.200 --local-port=7000 --null-audio
Now the INVITE is sent to the proxy:
INVITE sip:127.0.0.10 SIP/2.0
Via: SIP/2.0/UDP 127.0.0.100:6000;rport;branch=z9hG4bKPjRbQXYA1J.-vZts25XVKp.O-DOrb8p.Oo

Call-ID: TyaN6HBpuEor5uhdqhmNMyqe1ajo8CBb
CSeq: 998 INVITE
Allow: PRACK, INVITE, ACK, BYE, CANCEL, UPDATE, SUBSCRIBE, NOTIFY, PUBLISH, REFER, MESSAGE, OPTIONS
Supported: replaces, 100rel, norefersub
User-Agent: PJSUA v0.9.0-release/i686-pc-linux-gnu
Route: <sip:127.0.0.200:7000>
Content-Type: application/sdp
Content-Length: 456
Is it normal to have the proxy's URI in the first line?
Anyway, the proxy answers this way:
SIP/2.0 484 Address Incomplete
Via: SIP/2.0/UDP 127.0.0.100:6000;rport=6000;branch=z9hG4bKPjRbQXYA1J.-vZts25XVKp.O-DOrb8p.Oo;received=127.0.0.10
From: <sip:127.0.0.100>;tag=JZb1zvxWeh2TBgacIHAZpsOlGeWI8l02
To: sip:127.0.0.200;tag=3dd80deda90f5eedcb6114bfabf113a9.8449
Call-ID: TyaN6HBpuEor5uhdqhmNMyqe1ajo8CBb
CSeq: 998 INVITE
Server: OpenSIPS (1.4.2-notls (i386/linux))
Content-Length: 0
3. With the following configuration:
PJSUA_1 : --ip-addr=127.0.0.100 --local-port=6000 --null-audio --outbound=sip:127.0.0.10
PJSUA_2 : --ip-addr=127.0.0.200 --local-port=7000 --null-audio
I get exactly the same behaviour as at point 2.

So, what's wrong? I really don't know.
Thanks in advance.
