Is it possible to test sipp with spandsp to send receive fax to sip?
I have a good exe : spandsp_util.exe
It generates fax-stream and sends it to address:port
For example:
//to send a fax from 5000(operation port) to 4999
spandsp_util.exe -v -m tiff_to_fax -n complex.tif -F 5000 -f 127.0.0.1:4999
//to receive fax at 4999(operation port) from 5000
rem spandsp_util.exe -v -m fax_to_tiff -n test.tif -F 4999 -f 127.0.0.1:5000
So, if I have my complex.tif file and will start these 2 commands
simultaneously at the same PC,
I will have another(new) test.tif file at my pc after some time, so it works
greatly.
One person told me
Try mode "RTP echo from SIPp? "
http://sipp.sourceforge.net/doc/referenc ... + with + SIPp
And now I am trying...
.I have:
1)192.168.11.2 (my pc with sipp and spandsp_util)
2)192.168.11.3 (my sip device AP200B with number 500 +phone+fax-modem at this
number )
I tryed this command.
sipp.exe -rtp_echo -mi 192.168.11.2 -mp 6000 -sn uac 192.168.11.3 -d 20000 -s
500 -rp 2000 -r 5 -i 192.168.11.2 -l 1
OK, I have a sip call to my AP200B, it dropps after 20sec, OK
Now I am trying
sipp.exe -rtp_echo -mi 192.168.11.2 -mp 6000 -sn uac 192.168.11.3 -d 20000 -s
500 -rp 2000 -r 5 -i 192.168.11.2 -l 1
+
spandsp_util.exe -v -m tiff_to_fax -n complex.tif -F 5000 -f 127.0.0.1:6000
at 2 different consoles at my win pc.
I may be wrong or do not understand something. In ideal I want:
1) To here CNG at my phone ([email protected])
2) To receive a fax spandsp->sipp->ap200b(500)->my fax modem.
Is it a good Idea to try to do this test with sipp? Is it possible?
What is good parameters in command line for my case.
P.S. The feacher I want to try is exist in OPAL, it works greatly for t38
calls, but there are some problems with g711(audio) fax mode(I can here CNG/CID
but no sending-receiving). So I want to try another SIP (WIN) application for
SIP signalisation to try to understand this problem
Best Regards,
Dmitry.
