T.38 Receiving works, Sending doesn't

Post by ioan »

1. Brekeke Product Name and Version: Brekeke SIP Server 2.4.8.6/286.3

2. Java version: 1.6.0_05

3. OS type and the version: Windows server 2008

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

5. Your problem:

I have a BS and few T.38 end points running on amazon ec2. All those machines have a local IP and a static IP pointing to the machine.

We receive lots of T.38 faxes from different providers. All the providers point to the BS and from there I route the calls to different servers, for example:

Code: Select all

Matching Patterns:
$request=^INVITE
$addr=z\.z\.z\.z$

Deploy Patterns
$target=x.x.x.x
Now, for a new provider, we have to support sending of T38 faxes too.

I made the following Dial Plan:

Code: Select all

Matching Patterns
$request=^INVITE
From=sip:(.*)@
To=sip:(.*)@
$addr=x\.x\.x\.x$

Deploy Patterns
From=sip:%1@y.y.y.y
To=sip:%2@z.z.z.z
$target=z.z.z.z
When I try to send a fax, I can see the destination number ringing and then answers and after 10-15 seconds disconnects without any T38 messaging from our side reaching the provider.

As a note, if I put the t.38 endpoint on a physical machine, with static IP and I connect directly to the provider (no SA server used), the sending and receiving works fine. With BS in between and running on Amazon EC2, only the receiving part works.

Any ideas on what should I try?

Here are the logs from the BS:

Hi ioan,

Which version of Brekeke SIP Server are you using for this project?
You wrote 2.4.8.6/286.3 but the log indicates 3.3/379-7. Which one is the correct?


> Now, for a new provider, we have to support sending of T38 faxes too.

Who sends faxes? Are there any SIP client software which has FAX feature?

> When I try to send a fax, I can see the destination number ringing and then answers and after 10-15 seconds disconnects


The log indicates that the duration of the SIP session was 42 sec.
Is it the correct log data?

Hi James,

In production I use version 2.4.8.6/286.3, the log is from a trial version I downloaded on my development machine for testing, but I configure it to be the same as the production.

I send the faxes. To be more clear, BS and the machine that has the fax client are both behind a NAT on amazon ec2 and both have a static IP pointing to them. So, to send a fax, the fax client machine connects to BS and BS sends the call to the SIP provider.

What happens is that all is good until the client needs to switch to T.38, which never happens, the destination rings, it gets to handshake and then after a while terminates the call.

The client works fine if it's not behind SA on a machine with static IP.

Also, receiving faxes works fine with SA in the middle, the problem is only on sending.

ioan,

Does the above log indicate the problem?

According to the log, the session ended with the following line.
session.5: sipex.4: close: result=Success length=00:00:42.307 total-pkt=13 at 01/05/15 14:59:33.750

It seems the call length was 42 sec.

I'm guessing that the log doesn't show the problem. Is there a way to post the wireshark capture? Here is what happens on the fax client side (10.248.1.115 is the fax client and 50.112.120.253 is BS):

and here is the capture on the BS machine (10.x is BS machine and 199.x is the sip provider):

Screenshot of Wireshakr doesn't help.. because there are several mixed sessions, and there are no SDP in the images.

If you have support account with Brekeke, ask them to look at the packets.
