My experience with sending several subsequent short messages is that
this might run you into a timing issue. Whyever, some calls will not
successfully transmit the first two packets of the SMS handshake,
resulting in a non-delivery.

This can be seen on the CLI, so perhaps your problem shows up there as
well: Try
asterisk -r

CLI> set verbose 10

(keep CLI open)
and send those messages. I would expect those failing messages to show a
different pattern.

I got this failing probability _way_ down by using an additional Wait(1)
or Wait(2) in the dialplan where the SMS sending happens, after bringing
up the line and before sending the SMS proper.
