      Status: Waiting for Feedback  (was: Open)

[~LubosD], I got an EU version of the Gigaset and I've been testing this morning and have so far been unable to replicate the issue you are describing. Do you have the latest version of the firmware for the C530?

> I'm playing with receiving SMS messages sent by Gigaset C530 IP phones. I've set the SMS Center number to *88 and this is the configuration I'm using:
> {code}
> exten => *880,1,Verbose(Receiving SMS)
> exten => *880,n,Answer()
> exten => *880,n,Wait(2)
> exten => *880,n,SMS(sms_gigaset,as)
> exten => *880,n,Hangup
> {code}
> Long messages are delivered just fine, but short messages are messed up with 100% reproducibility. Examples:
> ud=@@ # This was "OK" 
> ud=Ah¥@ # This was "Ahoj"
> I don't know what else to provide. I've attached a debugger and tried to figure it out. At this point in the call stack (when sending a message with text "Ok"):
> {code}
> #2  0x00007fe1c3014d78 in sms_handleincoming (h=0x7fe1b4f28fa0) at app_sms.c:1134
> 1134                            p += unpacksms(h->dcs, h->imsg + p, h->udh, &h->udhl, h->ud, &h->udl, h->udhi);
> {code}
> there are these interesting values set:
> {code}
> (gdb) p p
> $19 = 13 '\r'
> (gdb) p/x h->imsg
> $20 = {0x91, 0xe, 0x21, 0x8, 0x9, 0x81, 0x37, 0x67, 0x56, 0x64, 0xf9, 0x0, 0x0, 0x2, 0x0, 0x0, 0x5b, 0x0 <repeats 233 times>}
> {code}
