[OpenSER-Users] INVITE NAT problem

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. When xlite sends a INVITE request
to openser, openser tries to send to SPA 921, but the PORT is still 5060,
instead of 22848. Therefore, Openser keeps resending INVITE to SPA 921 but
never reaches it. Both linksys and xlite do send preiodic SUBSCRIBE/NOTIFY
to Openser. Is there anything else I am missing?
