from what I can see, it could be because you don't have the
Proxy Address and
port...
also, your VoIP server may need the
Outbound Address and port too.
you can try the same as SIP Domain, or take that entry and (
if it's not voip.mydomain.com) run it thru
www.getip.com, into the little text window to trace another IP.
For instance, the actual
voip.mydomain.com shows an IP address of
216.34.94.184so the entries in the two blank fields would be ...
Proxy Address: 216.34.94.184 Port:
5060 ... (
unless your port is different)
Outbound Address: 216.34.94.184 Port:
5060 ... (
again, unless yours is different)
Some VoIP services may also need the
Register Timer(sec): adjusted , but start with above first and see if it works for now.
if your VoIP service fully supports the codec you entered, it's not a problem, but some providers use a lower grade compression, so setting the
Codec: AUTO, may also help to register to them.
I'd like to know if you're successful. It seems you're getting into the router, and if so, you should see the Web Interface UI pages... even on a MAC, web based is web based, or it should be... use the IP shown on the phone when you press the STATUS button after it finished saying
Optaining IP Address at the bottom of the screen... it could take up to 30 seconds to negotiate this, when first booted up, but faster after that if using "restart" option.
The STATUS button is the upper right top-most button.You CAN get into the Web UI using wireless, if your router actually sees the phone and created an IP for it, ... careful when connecting to OPEN Hot-Spots, you're fully open to hacking using the back-door entry account.If the phones address shows ... 192.168.0.105 ... so far so good, or if another one shows, it's OK too, just use the one that shows on the phone to go into your Web UI by typing it into the URL area of the browser ...
http://192.168.0.105 or whatever the IP showing on the phone is, and you should be able to enter your phones Login Screen.If it's the first time you entered into the Web UI, the default
name/pass is
admin/adminIF you forgot your login, use the back-door entry of
sadmin/sadminTell me if it's working...

... if it still isn't registering, you may have copied the password incorrectly, if you have it working on the MAC, but not on the phone, or one of the other pieces of info... really, ... the phone should connect... especially if the computers softphone connects.
I have 3 different accounts for SIP and real DID service, and with a bit of trying, got them all to register, using the above info.
You don't have to log-out of the Web UI each time you make a change, ... after saving the change (clicking save at the bottom of the SIP accounts), it will try to re-connect with the new changes ... watch the screen !
ONE IMPORTANT POINT, I just realized, in the NETWORK settings, make sure you've chosen the SIP account to activate for that NETWORK and click that separate button on the bottom of that page too, or the NETWORK you chose to use with your router will never see the SIP account you want, ... (I hope you realized that too, already
Good luck!
