i would like to know, what the best way is, to redirect an incoming
call from one fs (fs1) to another fs (fs2).

we use 3 freeswitch servers and the carrier passes calls to the three
fs servers randomly. if on fs server is not offline, the carrier sends
the call to the next fs.
this is generally good, but for conferencing it not so good.

i am using socket outbound and need to do this for conferencing. let's
say, we have a conference going on on fs1. another person wants to
enter this conference, but the call is passed to fs2. on fs2 we see,
that the caller wants to enter the conference going on on fs1.

now we have to redirect the call from fs2 to fs1. is this done with
"redirect" and some according settings/params or are there other ways
to do this? we would like to do this without our carrier doing
something, to be a little more independant.

thanks
dennis

i had a look at the deflect app, but as far as i understand it, the
carrier has to support/understand it ans react on the signals.

is that right or does this have nothing to do with our carrier? or
does this work between fs servers in the same local network?


another similar question is: how to reject calls, so that the carrier
tries to route the call to another fs? if we want to make changes to
fs and test them, we would like to block new incoming calls, till
there are no running calls, to shut down the fs.

What switch is your provider using?

sorry, i do not know that. i could ask tomorrow.

is deflect, what i understand? the provider has to support it? if yes,
what could i tell and ask the provider, to find a solution to this
problem? the provider is quite open for new ideas, although we do not
want to be to dependant on the provider and his possibilities.

Well its a standard SIP Refer, They may not support it for good reason.

so if they do not suport it (which has to be seen), is there another
way to redirect a call from one fs to another without the provider?
like redirect from one fs to the other over the local lan?

do they follow a 302 redirect? Because if the call isn't answered yet
then you can do a redirect

I've tried to do the same and in my own experience, most carriers don't
accept 302 redirects. What I've seen is they take the 302 as a failure
and move on to the next switch, so worse case with 3 switches, it will
take 2 retries before hitting the switch you want them to redirect to.

sorry, this is to difficult for me. what does that mean?

they pass a call to one of our fs. then we see, that the call should
be on another fs. we know, that the call is on the wrong fs, before we
send an answer. so we could react accordingly.

so at least they should react on a 302? this could help, although i do
not really understand, what happens on a 302.

if they support it, they would receive the target fs server ip where
they should try next with deflect?

if everything does not help and is not possible: what could i do else?
it would be very helpful, if fs would support another way, if the
provider does not offer specific features.

I agree with Ray ... using a 3XX series message is a bad idea ... or you could put OpenSer in front using the LCR module ... 503 to OpenSer and it would route to the next gateway in the gateway group.
I have yet to work with any carrier that handles 3XX series correctly except for some of the TCAP guys.

Could you set up the 3 inbound call handlers, then set up a 4th switch with the "conference" domain, or if you don't want to set up a 4th, designate one of the 3 inbound switches with a "conference" domain to handle all conferences, do media bypass and bridge the calls to the "conference" domain?

If you need to do load balancing, you could set up a conference_a domain on one switch, conference_b on the second, conference_c on the third, then use xml_curl to dialplan and bridge the call to the right domain...

But again, I am no expert... Just a noob trying to be creative.
