Avaya IP phones on non-Avaya IP-PBX? 2

[nixonmi]

Hi,

Does anyone has experience with Avaya IP phones on non-Avaya voice IP-PBX systems (Cisco UC Manager Express, Siemens HiPath/Hicom, Ericsson MD110 ...) ?

I suppose that SIP phones (9600 and expecially 9601) should have better interoperability with other vendors system, than H.323 phones (1600 phone serie).

Also, what is the opposite situation – Avaya IP Office and non-Avaya IP/SIP phones?

This situations are often when user migrate from one IP-PBX system to another, but prefer to keep previous phones?

Regards,
nixonmi

The licencing requirement for most systems and the loss of features/lack of integration makes doing this a false economy in the majority of situations, even using Nortel handsets on the Ip Office while supported is still a compromise on features and integration

So, it not possible (or hard) to license non-Avaya IP/SIP phone on IPO system?

One of the benefits of SIP should be better interoperability between different vendor's equipment. Sometimes we have request for Avaya's phones but on other IP PBX voice platform than IP Office.

Is the same situation with digital phones?

True, but only for limited feature set.

In thoery any SIP/H323 phone will register to any SIP/H323 gateway, and yes it would be more likely to work on SIP.

you wouldnt be able to program buttons on the phone, probably wouldn't get directory access, 'might' get VM MWI, etc...... Basically you would render most of the phones buttons pretty useless.

If you are going to mix and match systems, then spending money on Avaya/Cisco/Mitel kit would be silly. Just get some cheap Snom (or similar) kit and attach it to that.

They maybe IP Phones, but they are designed to connect to the kit they are for!

Not hard at all, but bear in mind that Avaya handsets can be programmed to do literally 100's of features on the buttons, SIP protocols do not allow that level of integration and each manufacturer has their own feature set and implementation of that feature set, many features bringing up a menu on the handset screen etc ..this is something it's impossible to standardise with the SIP protocol and nothing to do with limitations of Avaya/Mitel or any of the big players

Guys, thanks for answers.

So basic telephony functions (call, hold, transfer...) should work in situation when phones and IP PBX systems are from different vendors, but there is no guarantee (problem of licencing requirements).

Also most of advanced functionalities on phones probably will not work.

Exactly, you got it in one
