asterisk users - May 2016 - Sending Calls via SIP trunk from several different IP addresses from same Asterisk Machine, to the same destination IP

Hi!

I would like to reopen a discussion that I saw a couple of years ago, with the
subject  "Sending Calls via SIP trunk from two different IP addresses from
same Asterisk Machine"

The use case is simpe: There are providers that want to see a separate source IP
address for each of their customers SIP trunks. Now, if we have an asterisk box
with several customers, we have a problem.

Does anyone have experience in this topic? How could we send outgoing calls (to
the same destination IP) from different source IPs depending on the caller ID
(Based on From: field, sip account, preferred-identity, whatever).

I was thinking about some Kamailio, or SBC that would take the calls from
asterisk using a user/pass authentication on a single interface, and initiate
calls from a dedicated IP address for each customer.
Any better idea?

Thanks

Attila

Hi,

Usually, the trunk provider(s) provide a mechanism to support this, and
it's the "Tech Prefix" or just "Prefix".

So, for Tenant 1, send 12348005551212 and for Tenant 2, send 56788005551212.

They'll then strip the prefix, and send along to 8005551212

Most trunk providers worth anything will support this type of termination.

Hope this helps,

*Glenn @ VDO*

And if we were the trunk provider in this case - I would probably trunk it to a
separate machine, or run a second instance of asterisk on the same machine and
bind it to the secondary IP address / sip port combo, peer the two instances and
then send it out via the second instance.

Hi,

Unfortunately this is not the case.
For some reasons (separation, fraud detection) they separate the customer using
their source IP address. So I am still looking for some solution.

Thanks,
Attila
