Hello,
I'm interested in retrieving the reception time, in the UDP buffer, of the SIP packets handled by Kamailio. I see there is a "struct timeval tval" in "struct sip_msg", but this is the timestamp of reading the packet by Kamailio, so not what I'm looking for. According to the kernel documentation, this could be achieved using SO_TIMESTAMPNS on the socket: https://www.kernel.org/doc/Documentation/networking/timestamping.txt Do you think adding this feature to Kamailio could be useful ? To implement this we would need, I think: - Only buid this if SO_TIMESTAMPNS is supported (Linux >= 2.6.22) - Add a configuration to enable / disable this feature - Set the SO_TIMESTAMPNS flag when creating the socket - Add a field in "struct sip_msg" to store the new timestamp - When receiving a packet, read the ancillary data, extract the SO_TIMESTAMPNS information and store the timestamp in "struct sip_msg" - Provide a new PV to make this accessible from Kamailio script What do you think ?
