Hey guys! Freshly joined but seasoned in FreePBX and Asterisk. I'm having an issue with programming a DTMF key on a Grandstream phone. I'm trying to program a "Park" button to DTMF dial ##70# during a call. The problem isn't the phone or the function, the problem is that the End Point Manager uses "#" for comments or remarks in the provisioning file "cfg$mac". Is there any way to escape that so I can set my Grandstream function to =##70#? I have tried "##70#" with double quotes, '##70#' with single quotes. I've tried the unicode slash code for the # sign, I've tried the URL code for the # sign. I've tried escaping it with a \#\#70\# and so on. Is there any way to do this that anyone knows of?
Yes, I know I can change the ## blind transfer feature to something else but I still need the # on the end to help the call complete faster. My only other option is to log into the GUI of each phone and programming it that way. Not ideal but will work if I can't find another solution.
I'm currently running freepbx 2.10 on top of PBX in a Flash. Asterisk version 1.8. End Point Manager version 184.108.40.206.
Thanks for any help you can give me!
