Have any of you deployed a Grandstream GXW-4108 on asterisk?
Before I purchase one these, I have a question: I need to be able send a Flash() to get new dial tone after I’ve made one call in my dialplan to cause a 3-way call. Is this ability in GWX-4108 firmware?
legacy pbx station copper <=> GXW-4108 <=> FreePBX via SIP on VPS
