OBI202 - Unregistered Direct IP Dialing

Reading more of your posts I'm getting confused, which isn't uncommon for me.
Does n2vwz.dyndns.org point to the WAN address of your OBi/Sipura or does it point to tha WAN address of the Sipura across town?
n2vwz.dyndns.org points to my WAN address. wa2vcs.dyndns.org points to the Sipura across town. Our IP addresses are dynamic. Our routers automatically notifies dyndns.org whenever the IP address changes.
azrobert:
To call the Sipura across town set your OBi as follows:
Service Providers -> ITSP Profile C -> SIP -> ProxyServer : wa2vcs.dyndns.org
Service Providers -> ITSP Profile C -> SIP -> ProxyServerPort : 5064
Or use speed dial:
sp3(444xxx@wa2vcs.dyndns.org:5064)
For the Sipura to call your OBi he should have:
ProxyServer : n2vwz.dyndns.org:5060

Is the status of sp3 still "Registration Not Required"? Which is how it should be.
If you get fast busy after dialling **3, then there must be something more basic not right. Would you mind showing your Phone 1 DigitMap and Phone 1 OutboundCallRoute? Assuming phone 1 and 2 are the same regarding **3 operation.
Problem Solved! The Phone 1 Digit map was the problem. When I modified the string to add a secondary dial tone, I copied a working string from an OBi100. As a result, there was no support for SP3 and SP4.
This is the corrected Ph1 Digit Map string that is working:
([1-9]x?*(Mpli)|[1-9]S9|[1-9][0-9]S9|911|**0|***|#|**8(Mbt)|**1{t=di}(Msp1)|**2{t=di}(Msp2)|**3{t=di}(Msp3)|**4{t=di}(Msp4)|**9{t=di}(Mpp)|(Mpli))
This brought up the dial tone and allowed me to dial out. I was able to signal the remote Sipura, but there was initially no voice path.
Because the OBi is running behind a NAT, I also had to supply my WAN address to the X_PublicIPAddress field. I also tried using my URL (n2vwz.dyndns.org) in this field, but the Obi202 would not resolve the URL.
Adding URL resolution capability to the X_PublicIPAddress field would be a good feature for Obihai to add to the firmware. This would eliminate the need to update this field every time the IP address changes. I am aware that I could use a STUN server, but I don't want any 3rd party dependencies for Direct IP operation.

How does your config work if your proxy server (n2vwz.dyndns.org) points to yourself?
Edit:
Glad you got this working.
Sorry if I sounded like a jerk with the above post, but I really don't understand.
I guess I don't know as much as I think I do.

@ N2VWZ - congrats on getting it working!
@ azrobert - I share your confusion! I would leave these neutral:
Service Providers -> ITSP Profile C -> SIP -> ProxyServer : 127.0.0.1
Service Providers -> ITSP Profile C -> SIP -> ProxyServerPort : 5060
Then use speed dials as you suggest:
sp3(444xxx@wa2vcs.dyndns.org:5064)
That way any IP or dynamic address can be called.
