|
|
* Party A - transferee
|
|
* Party B - transferer
|
|
* Party C - target of transfer
|
|
*
|
|
* DTMF attended transfer works within the channel bridge.
|
|
* Unfortunately, when either party A or B in the channel bridge
|
|
* hangs up, that channel is not completely hung up until the
|
|
* transfer completes. This is a real problem depending upon
|
|
* the channel technology involved.
|
|
*
|
|
* For chan_dahdi, the channel is crippled until the hangup is
|
|
* complete. Either the channel is not useable (analog) or the
|
|
* protocol disconnect messages are held up (PRI/BRI/SS7) and
|
|
* the media is not released.
|
|
*
|
|
* For chan_sip, a call limit of one is going to block that
|
|
* endpoint from any further calls until the hangup is complete.
|
|
*
|
|
* For party A this is a minor problem. The party A channel
|
|
* will only be in this condition while party B is dialing and
|
|
* when party B and C are conferring. The conversation between
|
|
* party B and C is expected to be a short one. Party B is
|
|
* either asking a question of party C or announcing party A.
|
|
* Also party A does not have much incentive to hangup at this
|
|
* point.
|
|
*
|
|
* For party B this can be a major problem during a blonde
|
|
* transfer. (A blonde transfer is our term for an attended
|
|
* transfer that is converted into a blind transfer. :)) Party
|
|
* B could be the operator. When party B hangs up, he assumes
|
|
* that he is out of the original call entirely. The party B
|
|
* channel will be in this condition while party C is ringing,
|
|
* while attempting to recall party B, and while waiting between
|
|
* call attempts.
|
|
*
|
|
* WARNING:
|
|
* The ATXFER_NULL_TECH conditional is a hack to fix the
|
|
* problem. It will replace the party B channel technology with
|
|
* a NULL channel driver. The consequences of this code is that
|
|
* the 'h' extension will not be able to access any channel
|
|
* technology specific information like SIP statistics for the
|
|
* call.
|
|
*
|
|
* Uncomment the ATXFER_NULL_TECH define below to replace the
|
|
* party B channel technology in the channel bridge to complete
|
|
* hanging up the channel technology.
