VOIP trunk ICP330>Avaya IP Office

[jamie77]

A customer of ours has asked about the possibility of linking his IP Office in the UK to a Mitel ICP3300 in the US via VOIP trunks.

The IPO can support QSIQ signalling over H.323 VOIP trunks, will this be ok for the Mitel or will we need some kind of gateway inbetween the 2 systems.

I have heard a rumour that the Mitel will only support SIP. The IPO doesn't have this as yet.

Any help would be much apprieciated

Well, I have to be honest, Mitel is a little more ahead then our good friends at Avaya.

Mitel does actually support SIP Trunking, which the IPO does not (in terms of SIP, not H.323). H.323 is kinda old (it works however). By the end of September (probably before the begining of Sept.) Mitel will support SIP trunking (i.e. to Vontage, or other switches) as well as SIP to the desktop (say to an Avaya or Cisco phone).

Mitel does support Q.SIG over IP, but it's been modified for the SX-200 ICP and 3300 ICP only. The Avaya IPO maybe able to get away with it, however, I would not promise anything to your customer. It probably won't work. What you need is for the IPO to support true SIP Trunking.

There really is no way to make these switches work together, via IP-only.

I have set up a few of these system to link between each other, at present the only way i have done this is to connect via DPNSS, so basically you will need a Mitel acting as a gateway onto the IP Office, the IP Office now supports DPNSS.

Hope this helps

The IP Office doesn't support DPNSS.

It does support QSIG so you could use something like a Westel QSIG>DPNSS converter, but DPNSS can't be put straight into the IP Office.

DPNSS is supported by avaya,this is shown in a bullitin just under 2 years ago. you need to get a converter for this to work.

The Westell iQ2000 was co-developed by Avaya and Westell to convert Traditional DPNSS into Traditional Q-Sig (requires PRI card in each system).

The features supported by DPNSS are:


Call Back When Next Free

Call Back When Next Used

Executive Intrusion

Diversion

Three Party

Call Offer

Service Independent Strings

Call Waiting

Redirection

Centralised Operator Groups

Call Back Messaging

Break –in / Break-out

Anti-Tromboning

Distinctive Ring Cadence

Enhanced CPI

Dial Ahead

Trunk Pick Up

Remote Forward

Centralised Voice Mail

The IP Office does not directly support DPNSS, that is why you need a westell converter and these can retail at about £2000!!

Alt solution. Add 3300 controller to UK office, IP trunk between controllers, add Q-SIG/PRI card in 3300, run Q-sig between 3300 and Avaya. Not the cheapest way to go, but it works, done it many times.
Or, wait for Avaya to support SIP trunking, it is working now on 3300 for SIP providers but no other gurantees as intervendor operability. YMMV.

We are using the SIP trunking to an Asterisks box. WORKS AMAZING! I would deployee 3300's everywhere, but they don't want to pay for them. So there are some of us with functionality (Mitel side) and those with basic IP phones with minimal functionality (Asterisks users). As long as I'm on the Mitel side, things are good.
