even if it is not an economically sensible then It will be pretty

[Alex Balashov]

An ambitious endeavour. Are you sure it's an economically sensible one, given 
that there are a variety of solutions already out there?

Re: [SR-Users] Several Asterisk on this same IP

[przeqpiciel]

I would like to create PBX platform, at now I faced to make drag ivr
creator. After that I would create option for record calls for client and
this is why I look for solution :)

[Alex Balashov]

Yes, though of course you would have to correlate the calls (most likely by

So, I can use Kamailio as SBC/Load balancer/registrar, Asterisk as IVR and
application server, and rtpproxy as media relay and recorder ?

Re: [SR-Users] Several Asterisk on this same IP

[Alex Balashov]

It can record, as can a number of other media relays.

 The most obvious way to implement the RTP port handling, is to first
 open the next UDP port in the OS, and then report that back in the
 Invite/200Ok. If the port cannot be opened, then simply try the next in

 line.

WHy not installing rtpproxy and proxying all rtp to the inside uase
kamailio to load balance them, it will be transparent on the inside perhaps
a cleaner solution?

Re: [SR-Users] Several Asterisk on this same IP

[Kjeld Flarup]

As I recall it is sequential, but not from the start everytime, it is 
incrementing all the time.


If You are running three servers, then with a 100% identical load, one 
would expect an average of 2 failing attempts per call.


The reality I see is however often very different RTP ports, most likely 
because load isn't 100% identical.

 You may not have enough calls for RTP port collisions to become

an

 issue. Otherwise, I'm not sure how you're avoiding it, since

Asterisk

 isn't aware of which ports from within the range are in use.

Well, indeed, but a sequential scan of many consecutive ports like this from 
the bottom of the same range can be quite a latent operation. So at the very 
least the allocation strategy would benefit from being random. Does Asterisk 
take that approach?

You may not have enough calls for RTP port collisions to become an
issue. Otherwise, I'm not sure how you're avoiding it, since Asterisk
isn't aware of which ports from within the range are in use.

Re: [SR-Users] Several Asterisk on this same IP

[przeqpiciel]

Maybe there is an magic device? I know that if we have an asterisk, that
become to us with default configuration of rtp ports sets to 1_2.
And each call choose the one port fron that range. So if we have several
asterisks with default configuratiin of rtp, there is possibilities to have
2 concurent calls each through another asterisk instance with this same rtp
port. Am i right?

So mqybe this magic device could see source IP address and route rtp to
correct adterisk?

We run multiple Asterisk instances since 1.4 and never configured RTP 
ports.


More challenging issues are the Asterisk DB, and the Asteisk home.

Trying to run concurrent instances of something like Asterisk on a
single host is very challenging for this, among other reasons.

I recommend containerisation of some sort, e.g. OpenVZ. Give it a very
lightweight "host" environment of its own, with distinct networking.
Then the full range of ports will be available to every instance.

Re: [SR-Users] Several Asterisk on this same IP

[Gonzalo Gasca Meza]

We face similar issues, we had 1 * server per VLAN, where each * had the
same IP address, we achieve this with NAT.

 <> Asterisk 1
 <> Asterisk 2
SIP LB <---> NAT <> Asterisk 3

Your NAT device needs to be SIP aware, in our case we use Cisco ASA
appliance device/ I know there is a ASA virtual device now which runs in
VMware.

Hope it helps

HI,

Thank you for your respond. Obviously, I could set a port range per
instance of Asterisk but I though about something more dynamic. But when I
think on it more deep there is no any other solution.

Not entirely sure but you may be able to range them 0-0 for dynamic
allocation and let the kernel handle it.

Can you not assign different Asterisk instances different ranges of RTP ports 
to allocate from?
