I have Asterisk running on a Dell D600 laptop (its broken screen disconnected) this is slotted into a rack and has been in constant use for over 3 years. I use several different VoIP providers inc Sipgate,Voiptalk, Heart Telecom and even Tesco Internetphone and apart from tesco not registering when dynamic IP changes - a quick reboot sorts this out - I have had no problems at all - voice quality is comparable with standard landline. I use SIP internally with both hard & softphones and IAX2 and SIP (with STUN) on the VoIP trunks. The PSTN is handled via Sipura SPA3000 and I have several hard phones connected throughout the house and office, a couple of SIP hard phones with the rest being normal phones connected to ATA's - no problems at all I'm currently messing about with a GSM gateway connected to another Asterisk box via an internal X100p card - I have it working - just need to connect this box to the Dell. I will say this tho' - all my VoIP traffic is on its own network having its own wiring, switches etc and only 'meets' the outside world at the firewall - no LAN traffic!! -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
