Obi110 plus SPA8000 as Poormans Analog PBX
stooba:
That would be great. The trouble is that such small SMD devices are often very difficult to identify, especially ones without markings. Still, any info might help.
The components that I'd like to identify are:
K1 - a relay (DPDT)
Q206 - a transistor (likely a MOSFET of some sort to activate relay coil)
C99 - capacitor (likely power conditioning for relay coil)
D150 & D151 - diodes (polarity of PHONE/LINE Ring and Tip lines)
D203 or D204 - diodes (for back EMF on relay coil)
Since the relay is missing, Resistors R38 and R39 are added as jumpers that connect the COM and NO pins to look as if the relay was present and activated all the time.
In the mean time, I am going to ask the Obihai support team for this information as well. I've yet to deal with them, so I don't know how helpful they'll be. I'd hope that they'd be willing to support me since this was their bad decision that I am trying to correct. Maybe they'll offer to swap out my units with some that are properly populated. Fingers crossed!

Perhaps someone with an Obi that has a relay can take pictures and you can compare.
Maybe the "Owner of the 1st OBi110/100 units in service in Canada & South America" should volunteer. I bet that Obi110 has a relay! ;D

Relay
This is a picture of the relay switch inside of my OBi. Dose yours look the same? ;D

LOL QBZ.
I guess they use different relays for the US and Canadian markets because my relay doesn't look anything like your relay:

Infin8,
Hi there friend, I guess we are on a first name basis now. :D
Happy Easter all--
