Incoming message is considered stored unsent

[PaulFertser]

I received an incoming SMS just in time for Zhone to check for stored unsent messages and it sent it back :)

Zhone explicitly checks for unsent, so this seems to be a modem bug...

Mickey, is there a way around this except checking twice?

[daniel]

Can you please show the portion of the log where you receive the message? Somehow I can't really believe that as incoming and outgoing SMS have a slightly different format. Did this message arrive at the destination?

[PaulFertser]

I checked several times that there were not any incoming message notifications prior to that. Nothing related to messages, actually.

And i can confirm that this message was really sent to me by friend and was immediately (heard that with GSM interference on speakers) sent back, he confirmed that he delivered the same message he sent.

[daniel]

I can't really see the correct way to handle this..

Apart from the issue that the modem seems to be broken in that regard (no wonder here) and we can't really do anything about it I believe the "feature" of zhone checking for unsent messages and sending them really has bitten us one too many times now.

We should just disable that as sending SMS is pretty reliable now, no need for this cruft to exist.

[daniel]

I removed the timer in zhone in commit [9c204f11bfc37d388c44acf639abb124fa832ab0] so this should be fixed now.

I don't know what we can/should do about the "incoming messages appear as unsent" issue, though. If you have any more ideas, please tell.
