Example:
exten => s,1,capicommand(malicious)
Hold:
Puts an answered call on hold, this has nothing to do with asterisk's onhold
thingie (music et al).
After putting a call onhold, never use the Wait application!
Example:
exten => s,1,capicommand(hold)
Retrieve:
Gets back the holded call
Example:
exten => s,1,capicommand(retrieve)
Helper applications
===================
app_capiHOLD.c
Puts an answered call on hold, this has nothing to do with asterisk's onhold
thingie (music et al)
After putting a call onhold, never use the Wait application!
app_capiRETRIEVE.c
Gets the holded call back
app_capiECT.c
Explicit call transfer of the call on hold (must put call on hold first!)
Example:
exten => s,1,Answer
exten => s,2,capiHOLD
exten => s,2,capicommand(hold)
exten => s,3,capiECT,55:50
Will ECT the call to 50 using 55 as the callerid/outgoing MSN
