I'm not using the COT method because eventually someone else will be using the OBI unit I have in the US. That's why I want to keep them independent. I currently have both because I'm in "Testing" mode. I currently have only GV #s, no SIP SPs, and yes, I do have separate GVs on each box (I'm no expert, but I've been dealing with SIP/Asterisk for a few years so I kinda know my way around). I'll check my codecs, although I haven't touched them since I got the units. Remember also that I copied the configuration on the "suspect" OBI (the one in Colombia) and loaded it onto my US unit, and it works perfectly in my known good unit. Also remember that my calls are random, sometimes they'll go through, and sometimes not.. both incoming and outgoing.
I used VNC, but I'll try to connect to the Obi directly tonight, I guess with all the problems I didn't think of that. Thanks for the advice. BTW, for whatever reason, the Expert configuration portal through OBI is giving me problems too. I access it just fine and can make whatever changes, but for whatever reason those changes do not get reflected in my actual unit; that's one oif the reasons why I just started VNCing to it. That and also because I like to monitor my phone calls while troubleshooting and because I want to be able to save configuration files while testing (I didn't see a way to do those two things through the Obi website)
Regarding the "cannot connect" blank page I get, I get this error message on the Obi page only, meaning while trying to access
192.168.1.xxx on the PC I connect to. My actual VNC connection to the PC is always active and alive! By the way, You might be thinking, "well, maybe he gets that message after just rebooting the unit" to which I say, nope, it happens all the time, and at random, sometime I would be able to see one OBI page (i.e. SIP1) but when I try to go to SIP2, I would get the "cannot connect" message. To continue answering your questions, Yes, I've been able to have 2-way calls. But everytime except once, they stop hearing me. I can always hear them. Only once was I able to talk for more than an hour without interruptions. Oddly enough that happened after several other "cutoff" incidents and without me making any changes. Later that day the cutoff incidents came back... That's why I keep saying Random, and that's why I think I got a defective unit, which is just screwing with my head Sorry about the long message, I just wanted to answer your questions and post as much info as possible to help in troubleshooting
