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

[Attila Megyeri]

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

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

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
