REFER problem

gorans · Post by **gorans** » Sat Jun 21, 2008 8:29 pm

1. Brekeke Product Name and version:
BSS 2.2

2. Java version:
1.5

3. OS type and the version:
Windows 2003

4. UA (phone), gateway or other hardware/software involved:
x-lite and Microsoft OCS and bandwidth.com trunk.

5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/ ... terns.html :
8

6. Your problem:
I have Microsoft OCS <--> BrekekeSIP (new beta) <--> bandwidth.com trunk. There is no firewall and all IPs are public. Call comes into MOCS and it is answered properly. After a few IVR steps, MOCS issues a blind tranfer (REFER). This REFER is directed to a x-lite softphone that is regiested and is visible under User Registrations. What I would like is for BSS to issue an INVTIE to x-lite phone and not forward REFER request to bandwith.com (they don't support refers). Plus even if they did, I really want BSS to bridge the audio and to server as a b2bua of kind. I have set the bc2bua setting in my advanced settings but I cannot seem to get that to work.

Thank you.

Are you using Brekeke PBX?
If not, try the Brekeke PBX because it works as a B2B-UA.
In my environment, I'm using Brekeke PBX and SIP Server as a bridge between OCS and ITSP.

If you want to use a transfer by REFER, you need to use BREKEKE PBX instead of BREKEKE SIP SERVER.

You can download it.

Hi

Brekeke SIP Server is a SIP proxy.. so it can handle a REFER as well as another SIP request. but it can not make a transfer by REFER.

Brekeke PBX can accept REFER and handle a transfer.
