CFU INVITE is being change by BREKEKE SIP server

8 posts · Brekeke SIP Server Forum

dchang Original post
1. Brekeke Product Name and Version: Brekeke SIP server Standar edition.

2. Java version:

3. OS type and the version:

4. UA (phone), gateway or other hardware/software involved:
Hitron MTA: CVE-30360 and BVW-3653

5. Your problem:
I have to Hitron MTA devices, MTA1 and MTA2, both can provision successfully on Brekeke server.

I have two line on each MTA device. On MTA1 Line1 I set CFU to transfer the call to Line2.
However when I call from MTA2 (either Line1 or Line2), after receiving "302 Moved Temporary",
MTA2 sends an INVITE to MTA1's Line2 but it is changed by the SIP server to an INVITE to MTA's Line1,
which sends "302 Moved Temporary" and both MTAs enter a Loop. and the call is never made nor forward.

PS: I have a packet capture from the SIP server, I'm new on this forum and I haven't find out how to upload it.
I'd appreciate if someone help me out here.
Laurie
Can you paste packets here?
Or, you can post the capture at http://www.pcapr.net/


and.. which version and edition of Brekeke SIP Server are you using?

Appreciate your replay Laurie.

Hi dChang27,

It is a bug in Brekeke SIP Server v3.1.

if you are using Brekeke SIP Server Advanced Edition, you can avoid the issue with the following DialPlan rule.
[Matching Patterns]
$request = ^INVITE

[Deploy Patterns]
$session = failover
$continue = true

If you are developing the MTA, let you use a unique Call-ID for the redirecting INVITE.
dchang
Hi lakeview,

Thanks for your reply.

I got two questions though:

1. by adding the dial plan rules, does it mean that the CFU is handle by the SIP server using dial plan rules, rather that being done by the MTA?

2. By looking at the captures packets. The difference between the SIP phone and the MTA is how they process the "302 response".
According to RFC3261 21.3.3 302 regarding to "Moved Temporarily", The client needs to use a new address (1000) in the "requestURI". Hitron MTA works as RFC3261 states.

The SIP phone however uses a new address in "requestURI" and in the "To header" field. Which is not exactly according to RFC3261.

Seems as brekeke SIP server uses the address request in "To header" field and not in requestURI.

My question is: Is this the bug you refer on your last comment?

Yes.

Which SIP phone product are you using?
Does it work well with 302 without any issues?

If Hitron MTA doesn't work but SIP phone works... can you tune the MTA?
Or, let you use the Brekeke SIP Server Advanced Edition.
dchang
The phone I use is GoldenNet Technology Inc IP phone ET-747S.

I just bought the Lincese for brekeke server, currently not thinking to upgrade it to SIP Server Advanced Edition.

Also the CFU on hitron MTA is done by adding proprietary MIBs to the SIP config file.
lakeview
Brekeke's developer team have tuned the Brekeke SIP Server to handle this kind of situation.

They will release new version within a week after some testings.
You can update your current installation and you can keep using your Standard Edition license.

I will post a comment again when the new version is available.
