Hi
Pls. help us in resolving the problem that the SIP proxy server changes the
Source and Destination port while replying for message. Pls. find the below
message for the Reference In below message A cisco ata device (which is
behind NAT with IP 192.168.10.52) is trying to register it self with SIP
proxy server IP 172.16.101.10 with SRC port 5060 and DST port 5060, but when
SIP proxy server replies back to the message the port number gets changed
i.e SRC port 53492 and DST port 5060. Is there any way by which we can fix
this port num.
ser never changes the source port number on udp, it always reply on the
same port it has received the message on.
Are you sure you don't have another nat or a firewall in the way that
does this?
Could you take the network dumps on the sip proxy?
