[asterisk-users] Sip REFER failes w/603 Decline (Policy), Polycom Phone

[William Stillwell (Lists)]

I have several sip stations that on a that are on a nat'd network behind a
nice friend firewall.. no audio path issues, 2 way audio works, etc,etc,etc.


However, I can't get any of my phones to Transfer or Blind Transfer..

I search and search, and well, just about gone nuts on this one.

Here is sip debug from pressing "transfer->blind->dial dest->Dial Key" (note
both stations do have access tot eh dial-dst ext of 202010)
