[cisco-voip] VoIP over Hardware VPN

[Jim Reed]

Thanks to all who responded.  Finally have it working.  Is a combination of simplifying the VPN setup on the firewalls and dealing with issues relating to how our MPLS network handles EIGRP and the associated routing therein.  Going to run some tests tomorrow on static route weighting but think I have most of it figured out for now.  Thanks to everyone for their able assistance.  It was invaluable and will make several people very happy - or at least as happy as they can be made! ; )

Again, Thank You...

Depends on the packet loss, if you are having packet loss you might want to look at iLBC (codec) and then Transcoding resources.

I agree. All phones, voice gateways, etc., need to be able to talk directly to each other - so EVERY subnet that has a phone on it (at least a phone you want to be able to talk to) must have connectivity to the phone at your house (and vice versa).

Unrelated to your issue, if you notice quality issues with calls you might consider using the g729 codec.

Jim:

I would check your allowed network lists on the VPN setup. You may be allowing the subnets for the CUCM and Unity servers but possibly not the DHCP subnet that the phone you are trying to call.



I am assuming that your voice servers are in a different subnet than the IP phone at your house and on the other end.

The phone is sitting here in my house and I can ping it from my computer at my house.  I can do an extension to extension call and leave voicemail which goes through.  However, if I do an extension to extension call or make an outside call from or to the IP phone via the telco then I see no rx traffic.  Thank You...

Jim,

Keep in mind that the RTP traffic does not flow from phone to CUCM to phone.  So you would actually need to make sure you can ping the phone from your hours and vise versa.

Okay, hate to be a pain but the phone is registered and when I call one of our main locations and enter the extension the phone rings at my house but am getting no voice on my end.  Seeing tx traffic on the phone statistics but no rx traffic.  Any thoughts?  Routing all seems to be in place.  I can ping the phone from the Call Manager and can ping the Call Manager from my home.  Have the phone in the same calling search space, location, etc., as the Call Manager it's registering to.  It's showing a g711 codec.

Thanks in advance for any advice...
