Situation  
connect client disconnects after 31 sec outbound calls only.  
inbound are ok  
on wifi it is ok  
so only on mobile carrier network  
device on carrier ip is behind CGNAT (assumed)  
rtp timeouts are not the issue as these have been adjusted to reflect potential issues for timeouts  
all other timeouts for connection SIP properties adjusted to see if it helps.  
Diagnosis  
This seems to be a re-invite issue, Asterisk sends re-invite to new connection using CGNAT address and it never receives a reply as the re-invite never makes it. It times out and disconnects 31 secs.  
Has anyone else using the connect client

1. Seen this
2. Come up with a solution.

Check your NAT settings in PJSIP Settings inside the PBX.  
Could also be a firewall issue if you have one in front of your pbx

Also, please check that RTP Timeout is set to 0 in the PJSIP device profile settings.

Hi I have been through the timeout settings. As I noted. the cause is the re-invite sent to the carrier CGNat’ed address (phone) after the initial connection is made and the carrier no longer has an established connection. Maybe its an australian thing !!  
Anyway if I use groundwire as a client then i dont have the 3 sec drop out. So what does acrobits do differently ?  
Basically it makes the connect client useless to me, Which I am disappointed with  
Over to Vitalpbx ? engineers please  
Solutions has been to use groundwire. A bit disappointed really.
