Short answer is no, and I've used the zaprtc driver without issue on a number of machines. The problem is basically phones use 8000Hz (per second) and computers are in multiples of 1024 and 8 * 1024 != 8000, so you can loose some audio frames, although for the most part you won't notice a problem. The last time I tested a zaptel source as a timing source it was only 99.2% accurate, although usual method asterisk employs of polling hardware is far from optimal. -- Best regards, Duane http://www.cacert.org - Free Security Certificates http://www.nodedb.com - Think globally, network locally http://www.sydneywireless.com - Telecommunications Freedom http://e164.org - Because e164.arpa is a tax on VoIP "In the long run the pessimist may be proved right, but the optimist has a better time on the trip."
