Any suggestions? Which brand do you recommend?
it depends on your budget. for high end we use siemens hipath 4000 but for cheap but reliable pabx i would suggest a panasonic.
Gamit namin Panasonic ang brand. We got it from their dealer: Chain Marketing.
Naka interlink via VPN/Internet ang mga PABX namin. We can transfer calls from one office to another.
What we got was the Panasonic Model KX-TDA200 Hybrid IP-PBX System
Chain Marketing Landline: +632-241-6935
For cheap unit, get the Panasonic.
For Highend, Get NEC. That's what First Class Hotels used in the Philippines.
If you want to try Chinese made units.. they're good for a fraction of the price of Panasonic... but better than the ones you'll find along Raon.. try Cogent Consulting (Edwin Ong email:ecogent*yahoo.com)
