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.
