In my opinion Obihai never intended for people to use direct ip addressing for calling. I don't believe it is part of their software regression testing, the admin manuals don't discuss it.
I don't know Obihai's intention, nor their testing, but IP addressing for calling is in the admin manual. http://www.obihai.com/OBiDeviceAdminGuide#_Toc367543138
(It's the last part of the manual before the specifications. hwittenb must have thrown in the towel and quit reading before reaching it. ;D )

I'm not familiar with that type of trace, but I don't see any entries for the IP Phone.
Log into the OBi200 and click Status then Call Status while you have a call in session.
You will be able to see if the RTP packets are being sent.
I suspect you won't see RTP packets flowing between the IP Phone and the OBi200.
You can check the connection between the OBi200 and OBi110 by defining a speed dial on the OBi200 like this: sp1(Phone_Number@192.168.1.101;ui=obi200)
Now dial the speed dial number from a phone attached to the OBi200.

and heres the same for the OBi110 (using a different call)

there are more lines in the tabele but most of the values are 0 except
Packets in jitter buffer 9
Jitter buffer length 190ms
Recieved interarrival jitter 4 ms
>One other note, the DX800 phone audio codec lists as "G.711a law" and "G.711u law" not sure if that makes a difference ?
azrobert:
This is what I would expect to see if the call had audio. When I have had audio problems the RTP packet counts were zero.
Do calls work from the OBi110? Just dial 3103 from a phone connected to the OBi110.
G711 is fine. I don't know why it's using G711U on the transmit and G711A on the receive.

mmm, OK
I dont have a phone to hand that has the connector required to plug straight in to the Obi's, I'll find one tomorrow and test it out again directly ... thanks to you both for your continuing help, I'm learning all the time :-)
