* \todo XXX Note that this function contains a very expensive operation that
|
||||
* happens for *every* incoming media frame. It iterates through every
|
||||
* possible call number, locking and unlocking each one, to try to match the
|
||||
* incoming frame to an active call. Call numbers can be up to 2^15, 32768.
|
||||
* So, for a call with a local call number of 20000, every incoming audio
|
||||
* frame would require 20000 mutex lock and unlock operations. Ouch.
|
||||
*
|
||||
* It's a shame that IAX2 media frames carry the source call number instead of
|
||||
* the destination call number. If they did, this lookup wouldn't be needed.
|
||||
* However, it's too late to change that now. Instead, we need to come up with
|
||||
* a better way of indexing active calls so that these frequent lookups are not
|
||||
* so expensive.

/*
