Is anyone configuring Grandstream series phones as 3rd party sip phones yet?
I can get mine to dial internally and access voicemail. Where I'm having problems is with BLF buttons and dialing out. Can't seem to get it to accept a full length phone number. When I preface with a 9 for the LCR, it give a "no response" error and when I don't use the 9, it gives a "404 not found"

Any help here would be appreciated.

The SMDR output from the system will show what digits have been sent.

It sounds like a dial plan issue on the grand stream.

You should have an entry similar to 9xxxxxxxxxx (though this won't work with 911 calls, but for testing it will be fine)

This will allow you to dial 9 + any 10 digit number (11 digits in total). This will then be handled by the lcr on the system to route accordingly just like any other phone (digital, slt, ipp, etc)
