NAT Blues

I am running TB 2.2 I have a Grandstream 2000 at my home office. I am able to dial out with no problems; however, I am unable to hear inbound ringing, and when other extensions try to connect to me they get a busy signal.

I have the routers on both ends with the correct settings. I believe that my config files have the correct settings as well. Not sure what I am missing.

Has anyone else seen this behavior, and if so, what was your solution?

Thanks,

Willie

If you told us your router,

If you told us your router, config file and phone settings we may be able to help.

Router

Scott,

I appreciate you taking time to reply. I have spent the day reading and trying to absorb all the threads relative to remote extensions via SIP and NAT.

My router is a D-link 655 on both the client and the TB server side. I have ports 5060-5082 and 10000-20000 forwarded on the server side.

After spending the afternoon fussing with the Grandstream, I dropped a Linksys 942 on to try instead with identical results. My sip_nat.conf contains the following:

port=5060
nat=yes
externip=mystatictserverip
localnet=192.168.1.0/255.255.255.0
externrefresh=10
disallow=all
allow=ulaw
allow=alaw
allow=gsm

I have reviewed the 942 phone settings; they are essentially stock from Kerry G's setup tutorial. As I indicated, the phone registers without a problem (as did the Grandstream). I can make outbound calls from the remote with no problems, audio or otherwise; however, the remote extension will not ring. When someone in my office trys to connect to my remote extension they receive a busy signal.

Thanks,

Willie

give this a try

i am no expert but here is what works for us in the sip_nat.conf file

nat=yes
externalhost=mstaticserverip
localnet=192.168.1.0/255.255.255.0

note that this assumes that your remote phone is on the 192.168.1.0 subnet.

we have exactly the same symptoms until we put these three lines in sip_nat.conf.

No it doesn't it contains the local network of the trix server. This is the traffic that is excluded from the NAT rule.
