AGN VoIP Questions with IP Office

[jgb5pmr6fcg567ot52iq]

I have a customer that may be ready to take the plunge into VoIP. We've signed partner agreements with AGN and I really like their service offerings, pricing and devotion to the IP Office. Unfortunately, there doesn't seem to be a whole lot of pre-sale IP Office documentation and setup information.

My customer currently has a 406v1 with a VCM 4, PRI and about 60 digital stations. They have a few remote softphone agents. At a minimum, I know I will need to install a VCM 30 with a possible upgrade to a 406v2 or even a 412.

I need some answers to the following questions...

1. Is it better to set up as H323 or SIP trunks? Does using AGN as H323 trunks require any licensing like the SIP trunk licenses?
2. Does call setup still use up 2 VCM channels?
3. If I use H323 trunks, is Direct media supported between the AGN trunk and a Avaya IP Phone on G729(a)?

Thank you everyone for your help.

emoore625,

1. SIP is only supported on firmware 4.0, which I do not think is an option for a 406v1.

2. This seems to be open for a lot of interpretation. I think I read a while back on this forum that someone ran some tests and watched sysmon and determined that YES, two VCM's were being used for a SIP call. Not sure about H323. I also recall someone saying this was a "bug".

3. Good question. Don't know the answer, but I am thinking NO because AGN is only "aware" of the public IP address you give them in your "control panel".

You should do some testing and report your results back to this forum. That's how we call learn!

You cannot use v4 on a 406v1.

The difference between a h323 trunk and a sip trunk between two systems is the SCN features. Over a SIP trunk you will only have the ability to dial users etc across the link. You wont get any blf updates across the link, nor can you run centralized vm across it etc etc. Any SCN Features will not ve available on a SIP trunk.

PlatinumGuy,

I emoore625 is asking about SIP verse H323 via an outside trunk provider (AGN), not IPO to IPO.

I think I have the same problem with a customer... Embedded stops running and the CF light on the back of the IPO 500 goes dark.

A powercycle fixes it. My distributor said they've not seen this behavior before.

Does your CF light go dark?
