Do you need true SBC functionality or are you just needing NAT traversal and/or transparent proxy.

Perhaps if you were to describe a bit more specifically what you are trying to accomplish it would help.

This is between our PBX and the telephone company.

Take a look at this for basics.  https://supportforums.adtran.com/docs/DOC-1826

Is the unit in place now and you are adding SIP, or is it a new installation?  Will the TA908e be doing NAT for the LAN?  Are there IP phones connected to the PBX now, on the LAN?  The more information you give the community, the more help we can be.

Re: HELP!!! eth0/1 to eth0/2 SIP SBC with 908e?????

We currently have an openscape pbx going to a mediatrix the goes pri to the adtran that goes to the telecom... The mediatrix is freexing and taking out the phones daily... I am trying to find a cheap and easy way to get connectivity between us and the telecom via sip to sip connection... The current method is sip to pri to sip which is not good...

I think that the openscape is failing to connect to the adtran as I got it to ring by just pluggin it into the adtran and calling in and out... Though there was not voice either way... Once rebooting the adtran the calling is now saying error.

thanks,

Is there a way to register the adtran to the PBX? The PBX does not seem to want to send anything unless the endpoint is registered.

thanks!!

Re: HELP!!! eth0/1 to eth0/2 SIP SBC with 908e?????

Yes, you can register the Adtran to the PBX (or the PBX to the Adtran if that's what you need).

It sounds like the best configuration for your needs is to create two SIP trunks on the Adtran, one pointing to the carrier and one to the PBX.  Then build voice grouped-trunks to steer the calls appropriately.

Each SIP trunk can be configured separately with whatever registration, codec, etc. is required by the other end.

This is different from transparent proxy which would be for a SIP phone going through the TA908e to a hosted PBX as an example.

Sorry for my lack of knowledge, I did not put the system in, nor am I a telecoms guy lol... Story of every IT persons life I guess...

Well, I have setup what you stated, two trunk groups and two trunk accounts routing to the sip servers. Do you know what the command to register the adtran to the pbx is? I don't seem to be figuring it out. I pasted the config below.

Re: HELP!!! eth0/1 to eth0/2 SIP SBC with 908e?????

OK, what is working so far?  Is "Ridgeville" the incoming telco?  When you call the PBX number from the outside do you see incoming SIP invites?  Things are pretty confusing as both sides have private addresses.  Your default route seems to be on the subnet that you have labeled as "Internal", which seems odd.

Is there a device at your site that is doing NAT between the incoming SIP trunk and the Adtran?

Does the PBX expect to register to something, or does it want the incoming trunk to register to it? 

You may need to get either a local consultant or someone from Adtran ACES to help you with this.
