ICE works that way. You could get any client claiming ICE support, and the result would be the same.

Thanks for the reply. But, pjsip inside PC does not work that way. It dialouts almost immediately. Please note the following timing:
18:17:46.626 pjsua_media.c ..Media index 0 selected for audio call 0 18:17:46.630 icetp00 ICE session created, comp_cnt=2, role is Controlling agent
Using the same CsipSimple code running on Nexus PAD with Android 5.0, comes back with the result as in PC: no delay at all.
A more complete trace follows:

It seems that pjsip and csipsimple have done the correct things. However, the Android 6.0 AlarmManager delays the "schedule timer" by 5 seconds, as shown in the following trace:
06-03 17:05:25.547 11685 11706 V Timer wrap: Schedule timer 142 in 0ms @ 147924787 06-03 17:05:30.557 11685 11685 V Timer wrap: FIRE Received TIMER 142 147924787 vs 147929782
Scheduled at 147924787 but fired at 147929782.
Anybody provides clue will be highly appreciated. Thanks.

This 5-second delay is actually a very serious problem with "User Experience". It could lead to a general reject of CsipSimple from the Android 6.0 marketplace.
Is there any "real" user of CsipSimple anyway as of today? Or, CsipSimple has been abandoned completely?
Try turning off "Resolve DNS SRV" under Network.

Thanks Joseph. I tried both on/off "Resolve DNS SRV" under Network. No difference.
It seems that Android 6.0 is THE problem. They changed the AlarmManager API design.
Has anybody encountered the similar problem?
ICE with Linphone does not have the same problem. Unfortunately, Linphone does not support TURN server. So, in case that both parties are under symmetric NAT, Linphone clients will be out of luck -- no voice or one-way voice, which apparently is much worse than CsipSimple. So, we are still pending, waiting for any solution for CsipSimple. Has anybody ever encountered the same problem?.
It is apparent that very few APPs enable ICE/TURN/STUN. Most APPs run with Asterisk server or the like, which relays all RTP traffic by default and most ITSPs enable "SIP Server Relay" also by default. So, the NAT/Firewall is a non-issue. Even though ICE/TURN/STUN, are supposedly the international standard to support the least cost RTP routing among P2P and TURN Relay, very few APPs are able to take advantages of it. So, we should consider this Issue as "closed", for lack of response and interest.
Whoever suffers the same problem is encouraged to create another "New Issue".
