State table stopping SIP registration



  • Hey everyone
    I am having some issues with my asterisk box and pfSense running together. 
    I have set my asterisk box to register with my provider, and they have just moved their servers.  I can successfully register to their old server, but I can't with their new server until I flush my state table.  And then after a few minutes it stops working again until I flush the table. 
    I am currently running pfSense version 1.2-RELEASE.  I didn't have this problem with the RC I was using (RC3 I think). 
    Any advice or help would be appreciated.
    Thanks
    -Eric



  • First, there is a bug in 1.2-release that keep states even on WAN ip change, keeping a broken connection opened. If you have a dynamic IP, please read the link below (and sublinks). If you have a static WAN ip, disregard :P

    Also, is it a new asterisk install? Wich version/disTRO? Did you changed version? Who is the SIP provider? Mine have a different incoming and outgoing port and IP, and asterisk 1.4 changed it's behaviour regarding that…
    Also, are you using PfSense's SIP Proxy?



  • Calling normal behavior a bug?  I don't think so.  That's the way the state table works.  You can alter the timeouts using the advanced portion of the firewall rules.



  • I have a static IP, therefore I can disregard that. 
    It is not a new asterisk install, I have been using asterisk for well over a year now.  It is plain old asterisk that I downloaded and compiled on my Slackware server.  Version was 1.4.19, but I have downgraded to 1.4.18.1 and it seems better, still times out sometimes, but it has been good for the last couple days.

    Provider is icall (carriers.icall.com)
    Not using the SIP Proxy, never have and never had issues.
