Mitel MiVoice Business/MCD/3300 / Re: SIP trunks
« on: April 10, 2009, 08:48:36 AM »
im using SIP trunks in my Lab from vitelity.net over the standard internet and can be shaky in high traffic times.
my customers successfully using SIP trunks have MPLS installed in their sites and that their SIP provider
my lab trunks work as good as SIP trunks on the Internet ever will.... remember the internet as a whole does not support QoS throughout... and also your customer will want to make sure that at least their Pipe and maybe their ISP do support QoS on their portion of the network...
SIP trunks uncompressed take 100k bandwidth cost PER concurrent call...
make sure you set up your COR so that fax machines going through the PBX dial out over standard PSTN trunks...(at least until t.38 really works)
