Right now, we have a pbx that auto-answers for extension-to-extension calls, but after the phone has been auto answered, lets the caller press one to cause the phone to start ringing. (for example, the person's not in their office so you want it to ring through to voicemail) I'm able to duplicate the auto answer using the SIP add header function since I have Grandstream phones. I assuming what I need to do is setup a feature that executes a macro when the user presses one. This macro would hangup the callee and then redial the callee without sending the extra SIP header so the phone rings instead of auto-answers. Any suggestions on how to do this? If there's another way, I'm open to that as well. TIA! Thanks, David Ruggles CCNA MCSE (NT) CNA A+ Network Engineer Safe Data, Inc. (910) 285-7200 david at safedatausa.com
