SMS messages carrying a higher priority are sent to the smsc first. After that,
they are on their own.

yes i know but if kannel can send SMS having high priority before the low
priority then it means it has the ability to send SMS in specific order. If
SMS –by nature- uses a store-and-forward scheme then how priority works with
kannel and why they implement priority queue in kannel drivers.

SMS –by nature- uses a store-and-forward scheme. Even if Kannel sends messages
out in a specific order, it doesn’t mean that messages arrive in the same order.
If it is important that messages arrive in a specific order, then implement a
system that waits for a final dlr state and after that send the next message.

Subject: Re: Problem of messages with same priority
But this is not good because if we already have thousands of messages in our
queue then how can is it possible to deliver new incoming message before queued
messages. I think it is duty of Kannel to take care of message sequence in the
same way as it take care of messages with different priority. Can anyone
suggest the solution to solve this problem? I want that Kannel work like FIFO
queue.
Also tell me if we use sms.time field of message then can we solve this
problem? because arrival time of messages having same priority will different.
so we can differentiate them with there time.

Yes, and despite Kannel honors order of arrival at first, if messages are
queued and retried is hard to tell what the final order would be, specially if
a bind or the whole service is restarted.

Note that is your sms provider/operator smsc who finally takes care of
messages. If Kannel send messages in 1,2,3 order to the smsc it
doesn't mean they will arrive in that order to your phone.
