Hi All,
I encountered a situation that somehow a UA keep on Registering with the server with the same IP but on different port. So SER, thought that there are multiple instances of the same username and save the various location into the database.
The problem is it registers so often that the memory is full not very long.
I suspect it has something to do firewall but I am not sure.
Has anyone encounter this problem before? Any hint??
For the time being, is there a way to limit the number of REGISTER message that the SER will take?
Regards,
TC Chan
Hi Chan,
I also faced a similar problem in which when UA sends REGISTER to SER from different IP address than what is present in the contact header of the REGISTER message, then SER actually stores two AORs for the UA, i.e. one AOR is the actual contact header value & other is the same username with the IP address & port from which I sent the REGISTER message. I am not sure for the reason of this kind of behavior. Anyone from the SER developer list should be able to answer this query. So also forwarding this message to developers list also.

No, no, this is not the way to go.
This is due to firewall in between. First, try to limit re-register time on device, in possible. THey will be flushed from database afer being expired.
Then take countermeasures as below: Solution that works:
* use nathelper module to ping UA regularly with short messages to keep firewall open. Add those parameters to ser.cfg: modparam("nathelper", "natping_interval", 10) modparam("nathelper","ping_nated_only",1)
* use normal NAT-ed strategy in the rest of ser.cfg (as you probably do now) - use fix_nated_sdp() and/or fix_nated_contact() where applicable.
