I have an OBi-110 device and it was working fine with firmware 2774 to bridge VoIP/PSTN calls with and/or without the Obi Auto Attendant (
aa). In other words, callers from PSTN or VoIP had no problem to reach callees on the VoIP or PSTN site, respectively, with and/or without the
aa.
Recently, I made a wrong decision to upgrade the OBi-110 device with the latest firmware 2824. Upon the upgrade, I noticed the Obi110 device gives the following problems:
[*]Firmware downgrade is no longer possible as others have reported
here. The process to downgrade the firmware ends up with this error message:
Firmware downgrading is prohibited.
[*]Firmware upgrade (reflash) is also not possible and the process returns with this error message:
Previous version identical to the update. Firmware not modified.
[*]When
SP1 Service::X_InboundCallRoute (this also applies to SP2) is set to default (ph), incoming and outgoing calls work OK. When
SP1 Service::X_InboundCallRoute is set to
aa, incoming VoIP call has no problem to complete on the Phone port when option #1 is selected. However, when a VoIP callee selects option #2,
aa accepts the option and the call goes dead after
aa announces
Please wait while your call is being connected. The
Status Call shows
Number of Active Calls: 2 and
Call History indicates the call from VoIP to PSTN was placed after the call was terminated by the OBi110 device within 30 seconds of the # key pressed.
[*]When
LINE Port::InboundCallRoute is set to default, the Phone port rings when there is an incoming call from PSTN port. Upon picking up the telephone handset, the call goes dead while the caller still hears the call is still in progress (ringing). When
LINE Port::InboundCallRoute is set to
aa and the caller selected option #2 when prompted by
aa, the Phone port won't ring and the PSTN caller keeps hearing as if the call is still in progress (ringing). The
Status Call shows
Number of Active Calls: 0.

At this point, I am clueless but thought perhaps reflash the same new firmware would fix the problem. A las, all I encounter is as shown on item #2 above. :( Without being able to downgrade and/or reflash with the same firmware, I am left with an unusable OBi110 device due to problems I encountered in firmware 2824. I am hoping OBiHai will come up with a better firmware to fix this issue.
