Hi Erel,

Could you add a UnRegister method for SIP library ? It is so much needed

Yes. It is different.

I made a test with X-Lite the famous sip softphone and Asterisk the open source VOIP PBX. After I register X-Lite to asterisk and then shutdown X-Lite, from asterisk console we could see the following debug information:

B4X: 
    -- Unregistered SIP 'cisco1'

<--- Transmitting (NAT) to 192.168.1.9:8668 --->

That is to say, the X-Lite sip phone told asterisk voip server to UnRegister it before close.

Now I make a same test with android sip library and asterisk. I call sip object's close method. Nothing could get from asterisk console. That is to say, asterisk the voip sip server has no way to know android application has shutdown. If other softphone call android sip phone it will show "calling" till timeout.
