Hi,
I am working on getting my two SIP phones behind firewall to talk to each
other. One client is SPA 921 and the other client is xlite; and I am
force rport for all SIP requests from clients.
It seems innecesary since Xlite adds by itself "rport" parameter.
When xlite sends a INVITE
request to openser, openser tries to send to SPA 921, but the PORT is still
5060, instead of 22848.
Why should it be 22848? the destination or source port? "22848" appears never
in your trace. Why do you know it should be port 22848?
Therefore, Openser keeps resending INVITE to SPA
921 but never reaches it.
What I see is:
U 48.133.200.20:5060 -> 48.133.23.45:5060
INVITE sip:1005@48.133.23.45 SIP/2.0.
U 48.133.23.45:5060 -> 48.133.200.20:5060
INVITE sip:1005@48.133.23.45 SIP/2.0.
U 48.133.200.20:5060 -> 48.133.23.45:5060
INVITE sip:1005@48.133.23.45 SIP/2.0.
U 48.133.23.45:5060 -> 48.133.200.20:5060
INVITE sip:1005@48.133.23.45 SIP/2.0.
U 48.133.200.20:5060 -> 48.133.23.45:5060
INVITE sip:1005@48.133.23.45 SIP/2.0.
Extrange.
Both linksys and xlite do send preiodic
SUBSCRIBE/NOTIFY to Openser. Is there anything else I am missing?
That doesn't matter now.
