Hi Harry,
thx for your remind and your kinds of help.
as you says in mail, Alice know directly the address of Bob, and will pass the ACK signal directly to Bob, That looks good.
but in fact , the ACK signal just printed in log, not sent out to network, neither proxy nor Bob received the signal. secondly i
start wireshark to capture all netwrok packet, and i didn't found any Ack signal out from the Bob machine.
so my question is , in tcp scenario, Aclice directy pass Ack signal to Bob are right ? and if i wan't all signal pass to proxy (192.168.17.151) ,how could i get this happen ?
Best regards.

Well, so far everything looks correct:
I take it that 192.168.17.151 is your proxy
Alice:
87261 at 192.168.17.151
Bob:
87262 at 192.168.17.151
So basically 192.168.17.151 is also your sip "domain"
Alice has registered herself from:
87261 at 192.168.23.200:2535
Bob has registered himself from:
87262 at 192.168.23.138:5858
So when the INVITE from Alice to Bob goes to the Proxy (192.168.17.151), it will resolve Bob's URI
and forward the INVITE to 87262 at 192.168.23.138:5858. Bob sends the Trying/Ringinh/OK via the route
the INVITE came, that is via 192.168.17.151. Alice now sends the ACK directly to Bob ,since with the OK she knows
the Contact address, which is used for all subsequent Requests (including the ACK), so it bypasses 192.168.17.151
and goes directly to 87262 at 192.168.23.138:5858.
So, if you wrote the SIP code for 192.168.17.151, you are right, you dont see the ACK (there) (-:

Harry

Hi ,
thank your answer first , please check the ack signal below
ACK sip:87262 at 192.168.23.138:5774;transport=TCP;ob SIP/2.0
Via: SIP/2.0/TCP 192.168.23.200:2503;rport;branch=z9hG4bKPj32d7f3c7b48c414bb2426f2bc4eef931;alias
Max-Forwards: 70
From: sip:87261@192.168.17.151;tag=a30e9922b5a44411bcc832acf0557f58
To: sip:87262 at 192.168.17.151;tag=1b2d0905aed44dd1b8a35f3e6243554b
Call-ID: f8cd6035b2d74e92a6fe2f7043313c7c
CSeq: 32447 ACK
Content-Length: 0
is the red part wrong ? it should like this "87262 at 192.168.17.171:5060" or not.
Best regards.

Hi,

i have debug the pjsip source file ,found the pjsip had sent out ACK like below :
ACK sip:87262 at 192.168.23.138:5774;transport=TCP;ob SIP/2.0
Via: SIP/2.0/TCP 192.168.23.200:2503;rport;branch=z9hG4bKPj32d7f3c7b48c414bb2426f2bc4eef931;alias

CSeq: 32447 ACK
Content-Length: 0
but in my application i use tcp connection with 192.168.17.151 as my proxy ?
in this ack signal, obviously it miss the router hdr , so the ack messge can't sent out to proxy ?
so my question is , why the other signal will include the router hdr, why ack without the hdr ? it's a pjsip bug ?

??? PJSIP UA2 API lost ack?
hi all,
My application used pjsip ua2 api to deal with sip message, in the scenario i answer the coming call ,and voice bridge was connect success, but the UAS will timeout for a moment .
i check the sip signal message, when answer 200 ok , UAC should send ACK signal, but it seem doen't send out by pjsip ?
is there something i missing when i answer the call ? or UAC should do something after received 200 ok signal ?
best regards!
