Besides, priority is part of the SMPP spec and you never know what the SMSc on the other end will do.

Suppose you make Kannel the way you want it to work: Send out the first message that you want to send first, and after that the other ones. Then still you are not sure that that particular message is received first on the hand set. It depends on your upstream provider and a lot of other things that you don't have control over. == Rene -----Original Message----- From: Alvaro Cornejo [mailto:cornejo.alv...@gmail.com] Sent: Wednesday, 18 August, 2010 19:42 To: adil nazir Cc: Rene Kluwen; users@kannel.org Subject: Re: Problem of messages comes first in Bearerbox Queue I'm not developper nor have programming knowledge so I can't help you with changing the code; However, I'm still wondering why would you want kannel to strictly respect the order of the message queue when there is ABSOLUTELY no way to control that once kannel passes the message to the smsc. In the same seccond you push your messages, the smsc is receiving thousands of messages from other sources and the system will mix them all so there is very little chances to get the messages in the same order you entered to kannel. IMHO it is WAY too much work for nothing.
