Pick the best codec Choose the best codec... Uhhh... Yah.
Okay, ulaw is used by all telephony equipment, so start with it
Unless of course, you're a silly European, so then prefer ALAW
G.722 is better then all below, but not as common as the above... so give ulaw and alaw priority
Okay, well, signed linear is easy to translate into other stuff
G.726 is standard ADPCM, in RFC3551 packing order
G.726 is standard ADPCM, in AAL2 packing order
ADPCM has great sound quality and is still pretty easy to translate
Okay, we're down to vocoders now, so pick GSM because it's small and easier to translate and sounds pretty good
iLBC is not too bad
Speex is free, but computationally more expensive than GSM
Ick, LPC10 sounds terrible, but at least we have code for it, if you're tacky enough to use it
G.729a is faster than 723 and slightly less expensive
Down to G.723.1 which is proprietary but at least designed for voice

int ast_channel_get_cc_agent_type | ( | struct ast_channel * | chan, |
char * | agent_type, | ||
size_t | size | ||
) |
Find the appropriate CC agent type to use given a channel.
During call completion, we will need to create a call completion agent structure. To figure out the type of agent to construct, we need to ask the channel driver for the appropriate type.
Prior to adding this function, the call completion core attempted to figure this out for itself by stripping the technology off the channel's name. However, in the case of chan_dahdi, there are multiple agent types registered, and so simply searching for an agent type called "DAHDI" is not possible. In a case where multiple agent types are defined, the channel driver must have a queryoption callback defined in its channel_tech, and the queryoption callback must handle AST_OPTION_CC_AGENT_TYPE
If a channel driver does not have a queryoption callback or if the queryoption callback does not handle AST_OPTION_CC_AGENT_TYPE, then the old behavior of using the technology portion of the channel name is used instead. This is perfectly suitable for channel drivers whose channel technologies are a one-to-one match with the agent types defined within.
Note that this function is only called when the agent policy on a given channel is set to "native." Generic agents' type can be determined automatically by the core.
chan | The channel for which we wish to retrieve the agent type | |
[out] | agent_type | The type of agent the channel driver wants us to use |

Get a device name given its channel structure.
A common practice in Asterisk is to determine the device being talked to by dissecting the channel name. For certain channel types, this is not accurate. For instance, an ISDN channel is named based on what B channel is used, not the device being communicated with.
This function interfaces with a channel tech's queryoption callback to retrieve the name of the device being communicated with. If the channel does not implement this specific option, then the traditional method of using the channel name is used instead.
chan | The channel to retrieve the information from | |
[out] | device_name | The buffer to place the device's name into |

Weird function made for call transfers.

This is a very strange and freaky function used primarily for transfer. Suppose that "original" and "clone" are two channels in random situations. This function takes the guts out of "clone" and puts them into the "original" channel, then alerts the channel driver of the change, asking it to fixup any private information (like the p->owner pointer) that is affected by the change. The physical layer of the original channel is hung up.
