problem in transferring a fax to the SPA2102 using v27ter at 4800 or 2400
I have the below problem ,please see customer symptoms below
“We are running inter-working trials on our T.38 Gateway system with three phone adapters including a Linksys SPA2102. This SPA2102 has been upgraded to the latest firmware (5.2.10) but we are having trouble transferring a fax to the SPA2102 using v27ter at 4800 or 2400.
The same test setup with the SPA2102 works with v17 and v29, and also works at v27ter when used with a Patton ATA or a Grandstream 'Handy Tone'.
Using Bladeware 1.01 to send to the SPA2102 at v27ter 4800 also produces the same failure.
As a fax receiver we are using Faxlab 4.5. This indicates that the TCF is not actually transferred to Faxlab from the SPA2102.
Attached is the faxlab log (cisco_v29_v27.fxc), the last two transfers in the log are for a v29 transfer and then a v27 transfer to the SPA2102, the the v27 one failed.
The SPA2102 syslog output for the v29 and v27 tests are in the file 'cisco_syslog_v29_v27.log'.
Also attached is a Wireshark packet capture this shows that the TCF is actually being sent to the SPA2102, but it only ever sends one NSF/CSI/DIS sequence.
The test setup uses a loop back server on 172.16.1.193 from the Aculab T.38 Gateway (172.16.1.81) to the SPA2102 (172.16.1.82)”
In the manual I found that the fax machine a speed should be between 7200 and 14400 and v27ter is not working in that range of speed ,I told that to the customer he told me that from the SP2102 t declares v27ter,v29 and v17 capabilities. I saw the packets and really there’s v27ter.
My question is SPA can work at 4800 or 2400 rates and is’t compatible with v27ter? I’m attached the logs from customer.
