I believe you're saying that delays (filled with silence) are being introduced into your calls. A2B won't be doing this deliberately, but may be causing it as a side effect. Things to check:
1) a call using R2 signalling delivered to a simple Asterisk dialplan functions as expected without delays
2) you've installed all the prompts that came with A2B correctly
3) your server has enough RAM; this could easily be caused by paging
4) your SQL server is tuned for the hardware it's running on
5) your load average isn't significantly above 1.00 (or 2.00 for a dual-core CPU, etc)
