BSS Not propagating the ACK From UAC to UAS

1. Brekeke Product Name and Version:3.8.5.2

2. Java version:1.8

3. OS type and the version: RHEL6.1

4. UA (phone), gateway or other hardware/software involved: sipp.351

5. Your problem: BSS is not passing/propagating the 200-ACK from UAC to UAS.


Set up:

sipp-uac --> BSS -->sipp-uas

$addr = 192.168.2.180

Hi, It seems UAC is 192.168.2.180, UAS is 192.168.2.130 and SIP Server is 192.168.2.56. Is it correct?
Is ACK well-formed ?
Does the same issue happen even if you use another SIP client such as Linphone?

Your IP assumptions are correct. ACK is well formed. If I remove the BSS from call flow and send the call from UAC(192.168.2.180) directly to UAS (192.168.2.130) then everything works fine.

Have you try another SIP client instead of SIPP?

Yeah.. because sipp doesn't have to forward SIP packets based on what SIP headers point.

If you paste SIP packets, INVITE, 180, 200 and ACK here, I can look at them.

I have installed the trial version of BSS and it is not happening anymore. Thanks for your help.
