 |
|
Hi!
My telco is Deutsche Telekom and they got about 30 SIP servers right now.
Currently I've set up a template for incoming calls in sip.conf and added
each SIP server by it's IP address like this:
[DTAG-in-1](DTAG-in-template)
host=217.0.16.103
...
[DTAG-in-30](DTAG-in-template)
host=217.0.20.99
I've done that to improve security and to be able to assign all calls
coming in via Deutsche Telekom to a dedicated dialplan context.
Unfortunately this approach is not scalable and it's a PITA to maintain a
list of server IP addresses since Deutsche Telekom will get more SIP
servers in the future. They've started to migrate the classic POTS/ISDN
network to VoIP, the goal is get it done by 2016. Customers with DSL get
VoIP directly, i.e. they need SIP phones or a SIP PBX, and customers with
a phone line only are converted by the MSAN. And they don't provide an
official list of the SIP servers  By some reverse engineering I found
out that all SIP servers are within a specific subnet. Is there any way to
match peers by subnet(s) instead of FQDNs or single IP addresses? If not,
it would be a feature really needed to be able to cope with telcos running
multiple or tons of SIP servers.
cu, Markus

I agree this would be a great feature to have. We have Voxbone DIDs,
and keeping track of 60+ SIP Addresses they have is a PITA.

Mucking in chan_sip to add this functionality is not something I'd
really want to do... matching there is complicated and anything to do
with chan_sip is prone to introducing some sort of regression. If we
were to add that feature it would certainly require tons of tests.
That being said...
When I was doing the new SIP channel driver for 12 (chan_pjsip) I knew
people would want this functionality and due to the way it's architected
there it was very easy to do. You can specify IP addresses and subnets
and they all get mapped back to a single entity (called an endpoint in
chan_pjsip).
I'm sorry this doesn't help you right now with chan_sip but I just
wanted to show that the future is bright and that we do listen. ^_^
Cheers,

Markus,
We are developing an Asterisk intrusion detection & prevention tool which will allow you to limit connections by geographic region (continent/country/region/city), and include/exclude IP subnets, etc.
If you are interested let me know off-list (we're looking for beta testers!).
Michelle

You could consider making use of opensips. We use it for inbound sip
connections and its fairly easy to get it to perform a database lookup
against a connecting IP address and pull out a record and pass that onto
Asterisk using a custom header. Asterisk can then trust connections from
opensips and you can read in the custom header and have the dialplan
decide what to do based upon the value.
