RE: [Serusers] Trying SNOM 200 again

I am forwarding this config again, it was rejected by the filter yesterday.

---greg

Here is the config. I don't recall processing ACKs in call flows. I thought they were part of the call state in t_relay(). I see that this ACK has a Route: message. Is this where I get the information about where to send the packet?

I don't think that snom is guilty this time -- 200 ACK is forwarded to SER and consumed there, an issue unrelated to PRACK. I guess that's a problem in SER configuration -- send us your config file please.

ps -- our spam filter started doing a too thorough job and requests admin approval for almost anything. bear with it until it is fixed.

Hi guys,

I am trying to get the SNOM 200 to work with iptel again, I seem to be having issues with the PRACK again? In the trace below my gateway is sending an OK after On trace F16 an ACK comes back from the SNOM, lands on the SER and dies. Did the previous PRACK eat the STATE?

This can be viewed until midnight (GMT-5) at my server at: http://stage.august.net/snom_index.html

Or the text below is the actual trace.
