Since we started using VOIPo supplied HT-286 ATA, we've experienced 1-3 ms audio delay with answering incoming calls - my wife is getting tired of saying "hello, hello, hello,..."

Initially, I thought the delay was caused by VT "internet forwarding" - I had to do this as my number has not been ported yet; There is a post about the very same issue on the Grandstream's forums

FWIW, my SPA1001 does not exhibit the same behaviour (same network configuration); unfortunately, due to session timer handling issue, I cannot use the SPA1001 to work around the problem

I'm interested in hearing if anyone (with VOIPo provisioned ATAs) notices the same behaviour

Cheers,
