[Asterisk-Users] Trouble getting SMS working

[Mick]

Hi, 

Thanks for your reply.
I'm a bit confused as to what is going on too.
I am only making an guess but it seems the phone can't see the asterisk messages.
If my understanding of the protocol is correct the answering side should send a 
link established packet (EST) to the calling party.

so when * answers it sends
-- SMS TX 93 00 6D 00 00 00...
93 being the EST,

but * doesn't seem to get a response after that.
From looking at app_sms.c (not that I understand any of it), it seems the
'no data' message  is printed out after a timeout waiting for a response.

When I initiate the SMS from *,
The phone answers and sends the EST which * receives.
-- SMS RX 93 00 6D 00 00 00
* replies with
-- SMS TX 94 00 6C 00 00 00
Which is a 'release connection' message (what ever that means :)
but nothing seems to happen after that.

All I have done so far is verify that data will come from the phone to *, 
but it seems that the phone doesn't receive or recognise the messages coming back from *.
I dropped my fixed line, so I am unable to test anything against the Telstra servers.
I am wondering if maybe something is not configured/behaving correctly inside the pap2 ?

I tried putting in a delay like you suggested, but it had no effect.

Thanks again for your help.

Mick.
