Audio delay at start of calls to VPN connected offices

[Shad0wguy]

Within the past week we received reports of 5 second audio delays at the start of a call between phones connected over a site to site vpn. Our vendor is claiming network issues, though nothing had changed prior to this happening. We see some long round trip times in system status but not all calls show up this way. If I try to ping an affected handset from system status frequently I'll see 2 of 3 packets get dropped. Strangely though if I ping the same IP from our Voicemail Pro server there are zero drops, and it is on the same network as the IP office. I'm at a loss here. Any thoughts?

So it's a network issue, something is different with the routing from IP Office compared to the VM Pro server.

I'm just wondering why your vendor isn't on site troubleshooting this? Isn't that their job?

Well There you have it there is a problem on the network between the IPO & The VPN the fact that you do not have the same issue form the VMC suggests that it may be localised to the IPO connection.

nice comment but in this case I don't see why this should be the responsibility o the PBX Vendor, surly it is for the Data Maintainer to resolve?

True, but since IT (or service providers & etc) always blamed the PBX it usually was my job (when I still were employed) to prove them otherwise and where to look =)

I don't have hard feeling against the OP for posting the question here but I feel that his vendor should have helped him enough so he didn't need to.

Very True VoIP issues are Always* yet the Data team never seem to have the knowledge required to maintain a VoIP network (one of the he great myths of VoIP perpetuated by advertisers)

They also seem to use a different Dictionary to everyone else regards "Nothing has Changed" I know of at least one case whe the following scenario has played out:-

Cust: Our Phones don't work
Tech Support: Have their been any changes to your Data network?
Cust: No...
<various attempts to resolve>
Tech Support: Looks like we will have to get an eng to site
Field Eng: Weren't these HP switches last week?
Cust: oh yes we have replaced our switches - But Nothing has changed




*Well I yet to see an issue where it wasn't.

They claim it is a network issue, which they don't support. Unless it was an IPO problem they will not assist.
