Can't drop calls

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Call a phone (fixe or mobile) with Sipdroid
2. Wait for the screen to display "XX%lost, XX%late, Codec"
3. Drop the call with Sipdroid

What is the expected output? What do you see instead?
The phone call should be dropped, distant phone should stop ringing.
Instead, the phone call is not dropped. On my android phone, I can hear the 
person's voice mail, but Sipdroid seems to be in asleep mode.

What version of the product are you using? On what device/operating system?
I a using Android 1.6 on HTC Tattoo.
I have this problem with versions 1.5.1, 1.5.2 and 1.5.3
With 1.5, everything is OK.

Which SIP server are you using? What happens with PBXes?
I am using ippi.fr server, I don't use PBXes

Which type of network are you using?
UDP

Please provide any additional information below.
I can see on my SIP server account that whenever I try to ring someone, it was 
actually in communication for a few seconds/minutes. But using 1.5 version, the 
distant phone stops ringing and I am not charged any time.
