SMSOPS: body < 3 characters not transmitted (empty)

[gmaruzz]

Hello,

seems to me that if cellphone sends an SMS shorter than 3 characters (eg: "aa") it is sent as empty string

this maybe because of some snafu in PDU "payload" management in smsops_impl.c , pointer arithmetic between different characters' coding (ASCII, UTF8, UCS2, etc)

(tested with OnePlus 5t, 6t, Open5GS, SRSRAN)

I'm using Kamailio 5.3

I see after 5.3 there are at least 3 new commits related to payload management...
maybe is already fixed? can you check it out?

What about just giving a newer version (e.g. 5.6.x) a try? :-)

sms.zip
in the zip file two SMSs, one with payload "A" and one with payload "ABC"

(I'll check with newer version, if fixed would be nice to backport as bug)

[gmaruzz]

I confirm, is fixed in 6.1
would be nice to backport the fix

You probably mean 5.6.x? Thanks for the confirmation. Regarding backporting the fix, please note that 5.3.x is end of life since about a year. Please consider using a newer release.
