Problems with voice calls on Nokia 5110.

[Luc Damjan]

  Hello all.

  I use Nokia 5110 and gnokii. When I use --dialvoice <number> command. The
phone makes the call normaly. The problem occurs when the person on the
other end rejects the call and I try to call that same person again with
gnokii. The phone doesn't seem to respond.

  gnokii --dialvoice <number>    the phone makes the call
                                 person on the other end rejects the call
  gnokii --dialvoice <number>    nothing happens
                                 wait for 20sec. or more
  gnokii --dialvoice <number>    the phone makes the call

  I looked at the communication between the PC and the phone. Looks
something like this:

  The second call:

  Nothing happens.

  I wrote my own program to execute a call and to monitor further phone
responses. On the second call I get:

  If anybody has any idea please let me know. What are the meaning of the
0A(network status) frames from the phone and why the phone sends those
frames.

  I use Nokia 5110 software version: V 05.29 27-07-00 NSE-1.

  Thank you very much.
