How to call to IP Phone of Italy office using UC320W

[Sujish Sudhakaran]

We have supplied one UC320 box with 3 number of SPA303-G2. Now customer want to call to IP Phone of Italy office without adding any extra cost.

I can create a VPN between these branches. is it possible to call to Italy IP phones extension after creating VPN?

Please tell me want necessary changes I have to do this.

Bangalore(India) office current setup:-

1, SA520 (Internet lease line terminated in this)

2, UC320W with 3 number of SPA IPhones

3,  No FXO or BRI connection in UC320

4, they have one Panasonic EPABX for intercom and PSTN calling.

Hi Sudhakaran,

Sorry, currently UC320W doesn't support VPN and multisite extension to extension call. So your customer has to dial international number from Bangalore to Italy.
