Standard Phone

Page Index

For most phone models no direct control is supported. These must be configured as [Secial Device] = "Standard". The call setup is made via "Originate" command of the Asterisk Manager Interface.
Free hand mode via Call-Info : Answer-After=0
Some SIP phones supports an Auto-Answer via INVITE SIP-Header "Call-Info Answer-After=0". To force the Asterisk PBX to send this addiational header, a special patch is necessary.
  1. copy patch file to your asterisk source dir and then run the following command:
  2. patch -p0 -i originate_auto_answer_1.x.patch
  3. If this patch does not suite to your asterisk version, you can patch it manually according description in chan_sip.c.patch-originate-auto-answer.txt.

Ask your PBX vendor if this patch is supported.
