Hi,

I'm currently evaluating FreeSWITCH to see if I can migrate to it from
Asterisk (which gives me now all functions I need, but has some problems
with predictability). I need only one atypical functionality:
1. we have one main extension, which clients call. lets name it 5555
2. when someone calls 5555, then immediately rings only one
phone (1001) and 15 seconds later 3 more phones (1002-1004). phone
1001 should be dialled once per call to 5555
3. all phones (1000-1010) have BLF monitoring 5555, so anyone can
pick it up when someone calls it

ad 3. it is acceptable that all phones monitor 1001 instead of 5555 to
pick up connection to 5555

After reading and googling about possible implementation in FS for few
hours I couldn't find anything useful.

Could you tell if it is possible to implement in FS without artificial
limbs (i dunno if it's best English word for what I mean Smile like I had
to do in Asterisk?

greetings,
Seweryn

Seweryn,

Which phone(s) are you using? FS does BLF very well with Snom, Grandstream, and Linksys. Also, the dialing scenario you mention is actually very easily handled with FreeSWITCH. The devs are very clever and they set up a dialing syntax mechanism that allows one to do all sorts of unique and even exotic dialing setups.

Do you have a spare Linux machine and a few phones that you can do some testing with? That would be the ideal way to get started quickly. If you do have a Linux machine then the quickest way to get FS running is to do this:

Just remember one thing: FreeSWITCH is quite different from Asterisk, so there is a bit of a learning curve, but it's totally worth it. Smile

The default config demo's this.. its using the db app to store the
UUID and the intercept app to pickup the call.

I have Grandstreams and I have already tested BLF and "standard"
pickup on FS. It works great on default configuration.

are "bridge" and "sleep" actions + some FS's magic all what I need?

First I tried to compile FS on my workstation (Ubuntu) but it has
failed due to too new libtool. But on latest Debian it was OK and I
have FS console under my fingers.

BTW: it would be nice to have some notes about reloading configs in
"getting started docs" on the wiki.

OK, first things first, can I monitor 5555 with BLF? Because if not,
then we get to the same point like in Asterisk, where I do:
- redirect 5555 to 1555 on upper tier (PSTN)
- "terminate" 5555 on the phone with 1001 extension
- group dial 5555 and 1002-1004 with delay when 1555 is called
Now 5555 can be monitored with BLF.

The second thing (important only when using above trick) is: when there
is a call to 1555 and phone 5555 is ringing, can I pick it up by **5555?

Because if not, then again we get to the same problem like in Asterisk. In
Asterisk when rings the phone with 5555 extension you have to pickup
1555 not 5555. So on BLF you monitor 5555 but to pickup you dial **1555.
This is quite stupid, users can't have two buttons to service one
extension (one for BLF and one for pickup). To get it working
transparently for endusers on Asterisk I had to hack and slash
1555 and **XXXX extensions (ugly global variables involved).

The tip I can give you here is you have to set the
"presence_id=5555@domain" on a session so 1. the events are fired for
that... and 2. you actually get the BLF for 5555 Wink The presence ID
will allow you to set arbitrary things you can then subscribe to on
the phone.
