9508 and IP Office 500 v2

[grubb3]

I have a number of Avaya 9508 phones connected to an IP Office 500 v2 (I actually have three completely separate sites). Phones are directly on the chassis, not an expansion. Some sites have SIP, some have analog. One site is 9.0, other two are the latest 9.1 release.

In all sites I experience a problem where you cannot hear tone when you press the buttons on the phones. This occurs:
1 - When you grab an analog line out. You hear dial tone but no tones when you press the buttons.
2 - When you try to dial out to SIP. Press 9, no tone, and then you continue and it doesn't dial
3 - When you are on a call and you have to enter an extension number to reach a person, conference bridge number, etc. The call dials out fine but no tone is heard after this. This does not surprise me much as I experience this with every phone I use from time to time, even from a cell phone. You hang up and call back and all is well.

Issues 1 and 2 concern me. It is as if the phone itself isn't speaking with the IP Office unit correctly. It doesn't matter if using hand set or hands free, issue occurs both times. I also understand DTMF settings should not matter when on analog?

Any ideas? I'm stumped and so is my Avaya partner.

Grubb3, there are a few things that you must look at.

In order for the IPO covert (transcode) any signaling from DCP/ANA to IP/SIP VCM channels are needed. Check if you have COMBO / VCM32 / VCM64 daughter cards which gives you 10 / 32 / 64 channels.

IP-Endpoint licenses are also another component that you need in order for H.323 to work.

9500 series are digital therefore no need for VCMs, you should be able to go through your ARS Table and check 'Provide Secondary Dial Tone'.

Hope this helps.

Hi Wellington

Thanks for the response, much appreciated! Apologies, I should have been clear that this is an intermittent problem.

Any more thoughts?

It could still be a VCM issue. Did you check your resources tab under system status? Check your congestion counts and see if you have anything next to the VCM resource.

1 - Are the 9508s picking up local dial tone on the analog lines or are they dialing through another system?

2 - Are the SIP trunks local or on a remote site? This could be a VCM issue since it requires a VCM to place a digital to IP call.
