Hi. I have seen many posts on this but none have helped. Am running mISDN and Elastix 1.5 (awesomeness) I have never gotten this too work even when on Asterisk@home and Trixbox (Elastix is better!) Everyone keeps talking about pickup groups? Where is this? I'm sure its not ring groups as that doesn't make any difference in trying to pickup a call on another ringing phone. All help is appreciated as this has been a long fight with people who expect this as its a normal function. Thanks in advance!
