Hi,

My problem is in subject. As I read in documentations and
voip-info.org I can't user ChanIsAvalil because it not detects BUSY
information on SIP channel. I've tried to use SIPPEER function, but it
gives "OK (9 ms)" back on BUSY SIP channel. I use Asterisk 1.2.15, SIP
extensions are Linksys PAP2. Have any other idea?

Well?
Is it impossible to detect BUSY on SIP channels?

Place a call to it and if the phone reports BUSY, asterisk will return
BUSY.

Another way is to use the GROUPCOUNT set of functions, to keep a state
in Asterisk or to use the embedded call counter in the SIP channel
driver, that is reported in the SIPPEER function.

As often is the case, there are many ways to solve an issue in Asterisk.

not in stock 1.2
Bristuff has a function for it, and russell created a
function for it in current trunk that is also available as
patch to 1.4

So you have 2 possibilities:
- install bristuff 1.2 or 1.4
- install 1.4 with russell's patch applied

bristuff examples:

asterisk + function from russell:
