There is a bug in the Obi Firmware that prevents the no-once from changing as it should. This has been resolved, in an unreleased firmware version: 1.2.1 (Build: 2196M7C9DCA28)

I'd share the firmware but it was pushed to my device, and this not being an open source product, I'm not sure how to get it *out*, or if it would even be legal to do so.

Email support@obihai.com. They were actually very responsive about this issue.

You might be seeing something like this:

Currently IPSP-A is on google voice IPSP-B connects to my FreeSWITCH server.

Obi100 behind a Tomato-VPN router (port forwarding disabled [because it didn't help]). It's registering fine on an initial boot, but there's some weirdness.

FreeSWITCH is configured with a sip registration time of 3600 (as is the obi100). FreeSWITCH status shows the registration expire time is always 120 seconds max (it doesn't do this for any other device).

SipDroid stays registered and works fine behind the same router.

What happens is, it registers fine initially and reregisters every 30 seconds (this is good). After some period of time, it fails registration. The FreeSwitch folks thought this might have something to do with the nonce.

Trial 1: 14:54:32 registers - 14:59:05 fails Trial 2: 15:42:22 registers - 15:46:44 fails

I've tried STUN and ICE as well to no avail.

here's a siptrace:

Obi110​

Device has one line port and one phone port, can be configured with two ITSPs. FreeSWITCH works with the phone port as well as the line port. View the links mentioned in the dial plan below for explanations and more samples.

Obi110 FreeSWITCH Configuration​

Here is a sample of the user configuration, it is very basic:

Obi110 user directory

<include>
  <user id="7777">
    <params>
      <param name="password" value="some password"/>
    </params>
    <variables>
      <variable name="effective_caller_id_name" value="Analog 7777"/>
      <variable name="effective_caller_id_number" value="7777"/>
      <variable name="outbound_caller_id_name" value="$${outbound_caller_name}"/>
      <variable name="outbound_caller_id_number" value="$${outbound_caller_id}"/>
    </variables>
  </user>
</include>

Here is the the dial plan for handling incoming calls:

Obi110 dialplan

<include>
    <!--     This MUST be included in default.xml before enum!
     The Obi110 Line port is configured as SP(ans7777) to direct incoming
     calls to this FS extension. Incoming calls from Obi110 are treated as a call
     from an extension instead of a did so the DID does not work.

      <action application="voicemail" data="default ${domain_name} 100"/>
      <action application="hangup"/>
    </condition>
  </extension>
</include>

Obi110 Configuration​

Note the InboundCallRoute sets the user ID that FreeSWITCH will get for an incoming call.

The URI is essential for outgoing calls to work, otherwise the unit will dial its own extension (7777) instead of the correct number!

ITSP Profile A -> General - Fix DigitMap on multiple screens to match your requirements. It's probably easier to let FreeSWITCH handle digit translation.

ITSP Profile A -> SIP - Set ProxyServer and ProxyServerPort, to FreeSWITCH IP address and port.
