Cannot connect to Voicemail internally

[DXS_Matt]

Hey everyone,
I'm trying to get the free version of 3cx up and running before we purchase our Enterprise license, however I'm running into a deal breaking issue.

First let me tell you how things are setup.
Dedicated External IP -> Mapped to internal IP of 3cx server at 10.10.1.200 via our Juniper SSG-140
Local clients on the 10.10.1.x subnet

The 3cx server is up and running and I can successfully connect to other callers using the 3cx provided SIP phone client.

However when attempting to dial 999 the softphone connects, but I never hear anything. No prompts, no error speech, nothing.

Here is my log during the voicemail attempt.

11:40:02.397  [MS004000] C:1.1: (PASSTHROUGH): Can't send RTP stream to 0.0.0.0:42002 destination unreachable (298)

11:39:02.891  IP(s) added:[10.10.1.200]

As this is a directly mapped IP to our internal address of 10.10.1.200, there is no firewall on our 3cx server which is running windows 2003 enterprise.
All NAT destinations are mapped directly to the internal IP.
But the issue here is with internal callers trying to get to the voicemail system.

Am I missing a configuration step here somewhere? We just setup the system, no other configuration has been completed as we're waiting for our SIP trunk provider to get back to us with our provisioned accounts.
There are no inbound our outbound rules, no Digital Receptionists, call queues or ring groups.

Any help would be greatly appreciated as we need to have a working system in place by the end of next week.

Thanks very much,
Matt

Ok, so immediately after I finished writing the post above, I changed my connection string in the client to be 10.10.1.200 instead of 3cx.company.com.

Why would using the IP work but using the FQDN of the server not?

Thanks for your time,
Matt

Matt,

It looks like the FQDN "3cx.company.com" and address "10.10.1.200" are different entities, isn't it?

Thanks

No, internally, 3cx.company.com resolves to 10.10.1.200 on both the 3cx server and client attempting to connect, which has left me wondering why there is a difference.

As I said before, using 3cx.company.com allows us to call other internal extensions, but not access voicemail.

Thanks,
Matt
