Docsis chat

I need help regarding SIP on SBV5121E. Particularly I'm interested in:

1) Does it requires special firmware, what version and could somebody provide me with this firmware?
2) Is it possible to run SIP over TCP instead UDP with this modem?
3) Could somebody provide me MTA config file for such implementation?

I have a question related to the VoIP server (sip,mgcp). Which voip server, which sw and hw to use 3play services, provision of related services telephony.
Does anyone use an asterisk voip server and the user terminates.
Thanks

We are having issue with MTA that when a VoIP call established, there was no upstream voice at the very beginning of the call. We are using Arris 502 and 602 EMTA, and Terayon BW3200 CMTS. The upstream modulation is 16QAM. We have tried to enable DSX QoS in modem config file, but there were about 100 out of 320 MTA could not get online with the config file with DSX QoS enabled. MTA went offline immediately after received the modem config file. Those MTA were across all upstreams. Each time, the modem received the log as follows,

Hi
I have a C3 CMTS and MTA from Arris and SA.
My files don't have service flows, because the C3 create the service flows itself.
When use the Arris 501 I don't have delay, but a lot of delay wit SA DPC 2203, anyone has SIP working with C3 and DPC 2203 ?
Any idea to trace the delay cause ?

Best Regards.

Hi group

That's my question. We had one cable modem connect it to a cmts and the top speed was 2.5 mbps for download and ~1.2 on upstream for a config file with 4mbps. A person told me that cable modems only can achieved 2 mbps. It's true?

Info for the test:
BSR1000
For downstream, 64qam, 6mhz channel width, Symbol Rate 5.056941 Msps
For upstream, Channel Width 3.200000 MHz, QPSK, Symbol Rate 2.560000 Msps

Thanks in advanced
