DIDs calls among Ivozprovider clients

[Muhammad Yousuf]

Hi,

I am curious how Ivozprovider handles DIDs calls among different clients? I have a static DID range and want to make sure clients are not charged if they call those static list of DIDs let's say 042-3238xxxx and also calls to these DIDs should be routed within the ivozprovider.

Calls from one DID on ivozprovider to another DID on ivozprovider  are routed directly without going through your provider. You can verify that by viewing the live logs for the proxytrunks (using journalctl)

I haven’t evaluated if those calls get billed by the ivoz platform

I checked it but it's going through proxy trunks and then coming back into ivozprovider from provider.

Is your Caller a retail account on ivozprovider?

Also can you share a pcap of the call?

Yes both are retail accounts. One account calling DID of other account.

[Airsay]

So you are calling 9981 from 8000.  The below line is identifying the 9981 DID as an iVozprovider DID and routing it to the retail provider assigned to the DID:

MATCH-DDI: +92xxxxxx9981 recognized as +92xxxxxx9981 (b2c4ddi4dp1)

I don’t see the call being sent upstream of the proxytrunk to your iVozprovider SIP Trunk provider
