Just for reference: two SE-T610 minor bugs

 
> Here goes two minor bugs for T610, one is really not important and the
> other I don't know if it would affect anything because our CMG gateway
> also doesn't support it and Kannel is now patched to workaround it.
> 
> 1. Error in headers sent.
> SE-T610 sends an erroneous header in WSP data: "Connection:
> Encoding-Version".

> - After, there is a named header, "Encoding-Version" and a named value,

> I don't understand the "Connection: Encoding-Version". It seems like an

> As you can see, in mime part 2, you are defining data length as 7 bytes,
> but data is only six bytes, missing last 0x00 character. This is not a
> gateway error because other devices sends this packet correctly.

> This may cause problems with other gateways, but as I said before, our
> CMG version is not supporting multipart/form-data at all and thus I
> don't know its behaviour.
> In latest Kannel CVS version, I've assumed that a missing 0x00 is OK and
> thus T610 works.
