Hello,
Could anybody tell me what is the problem with such a configuration:
------------------- ----------------------------------------
--------------------
(UAC)192.168.10.1 |=======> |192.168.10.10 [OpenSIPS]
192.168.20.20|=======> |(UAC)192.168.20.1 |
------------------- ----------------------------------------
--------------------
The mysterious point is that all packets orginating from the interface
(192.168.20.20) towards UAC(192.168.20.1) have Bad checksum in the UDP
level. This happened with/without RTPproxy, so i'm wondering whether I
should care about this problem or not because the sound is conveyed
and everything
seems okay.
Regards.
