[asterisk-dev] Asterisk 13 and PJSIP 2.6 TLS Disconnections

[Ross Beer]

Hi All,


I'm trying to diagnose an issue with Asterisk 13 and PJSIP where TLS connections are being randomly closed by Asterisk. I'm currently testing the latest GIT version which uses Bundled PJSIP 2.6.


Phones are set to register every 120 seconds, so connections shouldn't be timing out.


I have a feeling this is related to the PJSIP keepalive options (https://trac.pjsip.org/repos/ticket/95):


PJSIP_TCP/TLS_KEEP_ALIVE_INTERVAL


I have tried setting these in the pjsip config, however, it doesn't appear to be working:


'netstat --timers -tn' shows that keepalives are not currently is use:


tcp        0      0 <DESTINATION IP>:5060      <SROURCE IP>:39395      ESTABLISHED off (0.00/0/0)
tcp        0      0 <DESTINATION IP>:22        <SROURCE IP>:61282      ESTABLISHED keepalive (195.31/0/0)
tcp        0      0 <DESTINATION IP>:5061      <SROURCE IP>:46216      ESTABLISHED off (0.00/0/0)

tcp        0    704 <DESTINATION IP>:22        <SROURCE IP>:59566      ESTABLISHED on (0.04/0/0)
tcp        0      0 <DESTINATION IP>:5060      <SROURCE IP>:39394      ESTABLISHED off (0.00/0/0)
tcp        0      0 <DESTINATION IP>:5060      <SROURCE IP>:46139      ESTABLISHED off (0.00/0/0)



Would SO_KEEPALIVE need to be defined when setting up sockets in Asterisk?


Best regards,


Ross
