How do I configure as an Asterisk extension

(1/2) > >>

sjpbx:
I setup ITSP Profile A General:SignalingProtocol to SIP
Under SIP, I changed the ProxyServer to the domain name of my Asterisk server
Under Voice Services SP1 service, I added my extension number and password.

The extension does register, but it doesn't stay registered.  When it is registered, I can call the extension from another extension in the system.  However, I cannot make any outgoing calls from the extension.  Eventually, I get a message indicating the the Asterisk server isn't responding. 

I've set up SPA3102, PAP2, and handytone 286's up as extensions with no problems, but this doesn't seem to work. 

Thanks,
Steve

Hi,

I set it up using the settings found here. Note that this may not be the ideal settings, but it worked for me.

Note: May not be necessary to include Register String

I don't understand why you have to set up a trunk.  I don't have a POTS line, so nothing is connected to the line port.  With other FXS's I used, the device uses SIP to connect to an extension on the PBX.  Do I have to setup a trunk in Asterisk to use the OBI110 as an extension?

Thanks,
Steve

In a word, no.  If you use the OBiTalk portal or the configuration wizard to set it up, you shouldn't have an issue, providing you are giving it the proper credentials.  You did not mention FreePBX, so I won't say anything specific about that, but using the OBiTALK portal you would simply set it up as a "Generic Service Provider", put the address of the server in the "Service Provider Proxy Server" field, use 5060 as both the Service Provider Proxy Server Port and the Outbound Proxy Server Port, and fill out the User Name (that will probably be the extension number unless you're doing it differently) and Password with the proper credentials (leave Outbound Proxy Server and URI blank).  Watch the Asterisk CLI to see if it registers after you submit the changes and see the device reboot.  You can also do "sip show peers" from the CLI to see if it's registered.

If you still have problems, it may be a firewall issue.  Try setting qualify=yes for your extension in Asterisk - sometimes that will keep the firewall open.

Also you didn't mention whether your device is on the same local network as the server or remote, but make sure you set nat=yes on the server if it is remote.  Do not under any circumstances use nat=never with an Obihai device; it won't work.  Use either yes or no (and yes works in most circumstances).

Hope that helps.

Hi,

I peered the Obi with Asterisk so that the SIP accounts configured on the Obi would be available to the other extensions on the Asterisk box. The Obi used in that thread also did not have Pots. It was not the intended use of the Obi unit.
