Dear SIP fans, I am looking for information on NAT time-out problem.
NAT keeps a state table of the existing connections passing through it. However, if there is no traffic on a particular channel, the connection will be closed after the NAT time-out period is over. There is a draft to keep a SIP session alive by using UPDATE or re-INVITE. This does not solve the problem of data channel. My question is how to keep the data channel alive? Thanks.
