------------------------------------------

The chan_sip channel driver is in 'extended' support status and is supported only by community members.  Your issue is in the queue. Your patience is appreciated as a community developer may work the issue when time and resources become available.

Asterisk is an open source project and community members work the issues on a voluntary basis. You are welcome to develop your own patches and submit them to the project.[1]

If you are not a programmer and you are in a hurry to see a patch provided then you might try rallying support on the Asterisk users mailing list or forums.[2] Another alternative is offering a bug bounty on the asterisk-dev mailing list.[3] Often a little incentive can go a long way.

>     When some endpoint goes offline the following messages appear in the console:
>  ERROR[2889]: tcptls.c:553 ast_tcptls_client_start: Unable to connect SIP socket to IP:5060: Connection refused 
> followed by 
> ERROR[2751]: iostream.c:569 ast_iostream_close: close() failed: Bad file descriptor
> Error occurs only for endpoints with protocol=tcp in sip.conf (and probably tls) after some time calls started to drop with "Bad file descriptor" errors and finally after some time Asterisk becomes unresponsible: all endpoints lose their registrations, no calls can be made/received. 
> Service restart does not help. 
> Server restart can help for a short time. 
> Workaround is to remove offline endpoint from sip.conf
> sip.conf example:
> [phone1] 
> type=friend 
> host=10.10.8.8 
> port=5060 
> dtmfmode=rfc2833
> context=office
> directmedia=no
> qualify=yes 
> transport=tcp 
> allow=!all,alaw,ulaw,g722 
> checked versions:
> 16.3.0
> 16.5.1
