[Asterisk-Users] PBX functions and different channels grouping

[Elman Efendiyev]

Hi All,

I need to replace old analog PBX with Asteriskl and X-Lise SIP
SoftPhones as client phones.

First: I have problems with implementation of PBX functions. I need and
unsuccesfully tried theese functions (took info at
http://voip-info.org/wiki-Asterisk+PBX+functions)

Call Pickup: Supported in the standard installation (*8 - defined in
res_parking.c +54)
- Just don't understand how to define pickup groups

Unattended Transfer (or "blind transfer"): Implemented in Asterisk (#),
optionally also in the phone 
- when I press # on X-Lite it hangs up

Attended transfer: Implemented in Asterisk (FLASH)
- How nj make FLASH on X-Lite?

Call Pickup: Supported in the standard installation 
- How to use it?

Automatic Call Distribution: ACD
- is it possible at all?


Also I tried Transfer command like this:

exten => 9,1,Transfer(SIP/234)

And when I press 9 got thiss error:

-- Executing Transfer("SIP/233-b6ad", "SIP/234") in new stack
Jul 24 16:34:09 WARNING[213006]: chan_sip.c:673 retrans_pkt: Maximum
retries exceeded on call
86FBDD7E-1E3F-4142-8C2D-FA112622A520 at 192.168.1.1 for seqno 102
(Non-critical Request)

Where 192.168.1.1 IP of SIP client calling from (233 phone)


Second: Is it possible to group different channels? I need thing like
this:

Try to call ZAP channel, if it's busy (or another problemm with it) then
try to call H323 channel, if busy again try to call IAX2 channel

I found info only for ZAP  channel grouping and dialing channels
simultaneously

Please help me with theese problemms
Thanks!
