Thanks, appreciate the insight.

If not get them on the phone, armed with your own captures showing appropriate RFC2833 event duration and if you yell loud enough they'll setup the instrumentation on their network to trap it. My guess, L3 isn't terming the call themselves and at some point the converting RFC2833 to inband to hand off to the eventual term carrier, and that carrier is accepting the call via a Sonus which is mucking it up. and yes been there done that. -- Robin D.

I have managed some Meetingplace deployments, there are goods and bads to it. Anything specific you need to know? Overall I'd say MeetingPlace has much better reporting, partitioning (users and groups defined in a way other than the BroadWorks AS), and general configurability than AL/BroadSoft (you know the BS solution is (or was?) AL's rebranded right?). The BroadSoft is just really nice in the way it integrates for users of the system, if that is relevant for you. Biggest issue is probably licensing costs. The newer versions can integrate or provide a local instance of WebEx too, which is pretty cool. I've also spent a lot of time trying to turn Asterisk into a conferencing product, but it seems to have timing issues keeping the channels in sync unless you have TDM-based (zap, not ztdummy) timing, or at least it did a few years ago. You can build a pretty decent feature set if you have the time though. -Scott -----Original Message----- From: voiceops-bounces at voiceops.org [mailto:voiceops-bounces at voiceops.org] On Behalf Of David Sarvai Sent: Monday, March 22, 2010 5:10 PM To: VoiceOps Subject: [VoiceOps] Conferencing Solutions Hi, I am looking to bring our current Global Crossing Conferencing solution on-net, and have begun to search for hardware/software solutions. I am looking at Radvision, Cisco, and now Alcatel-Lucent. I want to use SIP trunking between to the new platform. Has anyone in the group deployed anything other than Broadsoft's 3rd party Conference Server and are there any strong recommendations?

Thanks to all, turns out to be an issue with a sub-tending carrier for L3. Still working to resolution.

Anyone experience anything similar? Thoughts? ... G.711/RFC2833/L3 I've found that increasing tone.dtmf.level on the Polycom phones from the default of "-15" to "-12" or "-9" often helps with problems where conference bridges, IVR systems, etc. aren't receiving some/all of the digits. If that doesn't help, you will need to work with L3 support. They have had numerous DTMF issues with their gateway vendor over the years, and you may be running into the next in a long line of bugs from them.
