Problems adding IP phones to our current(all digital) IP Office 1

[indefinitedrums]

Hello,
We currently run IPO 500 v2 (PRI) with ~20 digital phones. Recently it was decided that we'd begin migrating to IP phones, so we ordered a few Avaya 9641G IP Deskphones to test it out. Our vendor came in today - we added the endpoint licenses, setup a SIP extension(then reboot), and assigned a phone a static IP. We registered the base extension to the phone, and logged the user with that extension into the phone without issue.
However - when attempting to call a local extension, we get a message UNOBTAINABLE; and when attempting to dial out, we get WAITING FOR LINE.
We did not change anything else on the system - I am not sure if we are to add lines(H323? SIP?), shortcodes, modify ARS, change to H323 extensions or what.

"H323 Gatekeeper Enable", "SIP trunks enabled", and "SIP registrar" is checked under System > LAN1 > VoIP
There are no VLANs, this is all on one internal network.

I have found a wealth of information online - but unfortunately do not really know where to begin. I'm asking to be pointed in the right direction. I will provide any additional info asap. Thank you in advance for any help.

Well first, those are H323 phones, not sip phones...so not sure why you put in a sip extension. You don't need to add lines or shortcodes or modify ars to make it work. It just works like any other phone.
Let me ask, do you have VCM channels? You'll need those.

Austin,
Thank you, this is exactly what I needed.

As far as I know, we do not have any VCM channels... although I wouldn't know where to confirm that.

Under System we have the following:

IP 500 v2 7.0 (23)

IP 500 v2​

PHONE2/PRIS U​

PHONE2/ATM4​

DIG ADPx30 RJ21​

I will replace the SIP extension with an H.323 extension(and read up on this in general). I assume that we will need something like the Avaya IP500 VCM 32 Base Card to add the VCM channels?

Again thank you for pointing me in the right direction.

Yep, no VCM's there. You'll need to get some flavor of vcm card, whether a vcm 32 or a combo card (includes digital, analog and trunk ports, plus 10 vcm channels). That may be a cheaper way to go, unless you plan on adding lots of ip phones.

We will likely migrate the entire office(still expanding) to IP phones over the next year or so - I think the 32 or maybe even the 64 would be a good buy.
I really appreciate your help. I have only limited experience with phone systems, mostly just managing users/huntgroups. I did set up FreePBX + Twilio last night in a testing environment and that was really fun - no licenses, no contracts, and can be hosted in the cloud. The future?

Have a great day, and thanks again.

IF you have the IP endpoint licences then the VCM32 v2 at about £130 is a good buy.

So your vendor came to site but did not spot that you did not have any VCM channels & were also configuring incorrectly

This should probably tell you something, I will leave you to draw your own conclusions...

Yeah, IPGuru, I didn't want to be the one to say it. :X

Yes, I am aware that this is a big issue - I really like working with these guys and they have never failed me on digital, but obviously this was a large oversight.
I was also told that we should just get a combo card w/10ch since "its only used to talk between IP and digital" - from what I see in the docs, VCM is used to dial out on our trunks and for placing calls on hold, etc.

We decided to get a VCM 64 base card(V1 since we are still on IPO 7.0).

I appreciate everyone's insight - I am a lurker here most of the time and I am always amazed at the helpfulness of people here.

Thank you all again.

Stay away from Combo cards for IP!! Having LOTS of Combo cards replaced with VCMs. Problems are mainly echo, stutters, cuts, cross-talk. Plus in SSA you see tons of alarms (Jitter). It all clears up once they are replaced with VCMs, including alarms.

@yankblan

Whew, thank you for the advice...

We went with a v1 64 VCM base card - and cancelled the combo card order the vendor placed

VCM channels are only sued when transitioning from IP to the TDM buss & during call setup.

My general rule of thumb is to have as many VCM channels as you have no IP trunks + a few extra to cover internal usage.
on a hybrid system you need to take into account the fact that calls IP to digital will require a VCM.

Update:

We installed the VCM 64 Base Card V1, and setup the extensions as H.323 and everything went great, took about 10m to get it going. Thanks again to everyone for their input. Now if I could just get these damn things to default to the headset I'd be good
