I have a 2102 being used for an intercom on my SIP network. The box is really just a speaker. It seems like in the past I got this to work before by making a switch to one or two settings that basically made the 2102 assume all invites would be auto answered and then all bye would end.
I found an article stating that changing the CPC to 1 would make it hang up. But I have two issues, 1 this is SIP and it seems like I would want it to hang up on BYE, and 2 that doesn't explain how to get it to accept all INVITEs.
It's driving me nuts because I swear I did this before a my job at the lumber yard with the same device when we integrated our new SIP network into our existing clunky intercom. I thought it had something to do with the port polarity.
If anyone has a clear answer that would be great. Thank you.
