 Posted: Wed Feb 18, 2009 2:57 am Post subject: 'Double' transfer failing with 403 error. |
 |
|
1. Brekeke Product Name and version:
Brekeke PBX, Version 2.2.6.2 , Pro Evaluation
2. Java version:
3. OS type and the version:
XP SP 3
4. UA (phone), gateway or other hardware/software involved:
X-lite and LinkSys SPA942
5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/networkpatterns.html : pattern 1
6. Your problem:
A caller on 4031 dials 4070. 4070 does not answer and is transferred to Voicemail (our own software that we are porting to VoIP) If the user does not make a selection from the 'front end' menu the VMS will transfer them to an operator extension.
This second transfer (VMS transfeering 4031 to operator) fails with a 403 error.
All extension involved are setup as UAs under the SIP server and as Users under the PBX.
Any help would be appreciated.
TIA

In both sucess and failure examples the REFER is sent by the VMS and the response (either 202 or 403) comes back from Brekeke.

Can you paste both 202 and 403 response packets here?
I want to look at them. |

Sorry for slow response. I have just had the chance to look more closely at my response packets and I think I have seen the problem.
I'll do some more testing and get back to you.
Thanks for your time so far

This is the 403 response packet
SIP/2.0 403 Forbidden
Via: SIP/2.0/UDP 10.1.0.121:7030;branch=z9hG4bK-29728-a1e7700-d63ec0d
From: <sip:734070@10.1.0.159:5060>;tag=67b20a0-7900010a-1b76-50022-29715-6aaa490e-29715
To: "4031"<sip:4031@10.1.0.159>;tag=b441f227ep
Call-ID: 357671f7-8721d7a9-65bcc1ec-7a3d17eb@10.1.0.159
CSeq: 1 REFER
Content-Length: 0
The reason for the 73 prefix on the 4070 'extension' number is because I have setup each user to divert to 73xxxx on no answer. I then have a dialplan that looks for the 73 prefix and patches the SIP header to provide my VMS with divert cpi. As far as I can tell this is something that the Brekeke IPPBX does not provide.
I have added 734070 as a UA (the test that I refered to above) and this has made no difference.
Below is the sucessful transfer response packet.
SIP/2.0 202 Accepted
Via: SIP/2.0/UDP 10.1.0.121:7030;branch=z9hG4bK-29992-a27e5bb-4dfea27d

Any help with this would be very much appreciated.

This topic refers (pardon the pun) to the dial plan issue that I mentioned above.

if you dial to 734070 directly without transfer, can you reach?
do you have an account of Brekeke Developer Support Program? |
