[SIPForum-discussion] The max duration of SIP conversation

[Karl Tian]

Hi badal,

     Thanks for your reply to my question.
     Now I've oriented the reason for sip conversation disconnect once
duration reaching to 72 hours. The SIP server I used for testing is of ONDO
types, and there is a configuration  "Talking timeout" with default value
"259200000ms", and I will make sure that by capturing packets.
     Best wishes
     Your Karl
