International Inbound Calling Issue

[oneglobaltech]

Hello all,

I could use some help with an issue we are having.

International inbound calls to a remote office (by remote I mean site-to-site VPN and 3CX server at HQ) extension is sent to straight to voicemail, user claims the phone never rings.

I'm able to make local in/out bound calls and I'm able to make outbound international calls to this extension.

It feel like a timeout issue, but I can't seem to find a parameter to tweak.

Any help is greatly appreciated.

3CX Ver. 7.1.7139.0
Win2K3 Server SP2
SIP Trunk
Cisco ASA

Thank you,
Chris

If possible, if you can replicate the issue, post a 3CX log showing the inbound international call that goes straight to VM and post a call that rings the phone for the set rings before going to VM.
