    have an Elastix server in an office and the router must port forward according to the manuals in remote extensions, so in Mark with the number once the extension is not available.

    I don't understand you so much...

    Your problem is the Remote Extension?
    What protocol do you use with that Extension?
    What's the results of (sip show peers or iax2 show peers)?

    Regards,

    Hi Mirko87

    Tks for your quick answer

    Yes my problem is with all my external extensions. My internal extensions work fine (can do calls accept calls, even internal calls between extensions) The problem is with external extensions:

    My office router is an ASUS with port 5060 open to my internal IP from elastix server and with ports 10000-20000 forwarded too.

    In my remote office I have an Linksys router and two Linksys SPA921 phones. I

    It looks like the typical double nat problem, unfortunately there is now one answer as there are numerous types of NPAT and each needs to be able to traverse all RTP and SIP signaling correctly. I quick fix might be to use ports other than 5060 for each of the SPA's (and expand your forwarding rules to suit) the audio then might or might work also, depending on how you set up each router, particularly the remote office router.

    Wellllll it turns out to be a missing configuration in sip_nat.conf. AS it was missing asterisk didn't know what was my wan/lan networks.
    It work fine now! at least with one linksys SPA-921 each one at a remote location.

    Hi.

    To the problem sip_nat.conf, you have lots of example into the forum!

    sip_nat.conf (With static public IP)
    • externip=your_ip_public
      localnet=192.168.1.0/255.255.255.0 (your local network)

    sip_nat.conf ( With a dynamic IP "DynDNS" )
    • externhost=your_domain_dyndns
      localnet=192.168.1.0/255.255.255.0 (your local network)

    The server name must be the same name that your external domain.
    • If your domain is elastix.homeip.net, your elastix server must be elastix.homeip.net

    Put nat=yes on each remote extension.

    Port forward:
    Sip - 5060 - UDP or UDP/TCP
    RTP - 10000 to 20000 - UDP
    IAX2 - 4569 - UDP/TCP

    Regards
