Description:I'd love to have 64kbps native zaptel channel bridging
so modem calls over asterisk get 48-52 kbps speed.
I think this could also improve echo problems.

What speed would you get now if for example you connected a modem to a zhone channel bank, dialed through asterisk (TE410P) back out to a RAS like MAX 6000?

I have euroisdn E1s in and out and when I dial through asterisk I get max
31200 kbps.

Thanks, I guess for now asterisk is not data friendly.  I would also like to see this feature implemented but sadly, do not have the skills to help with it.  However, I do have equipment that could be used for testing.

I connected a Win XP v.92 Lucent modem to a zhone zplex10b channel bank, dialed through asterisk (TE410P) and back out to a Lucent/Ascend MAX6000 RAS with MX60-SL-30M-S563 V.90 S56 III Modems.  Connect rates are GREAT!!!!  RADIUS and Windows XP report 52k sustained for a 30+ min call.  I plan to test it further with 96 data calls at the same time over a longer period.

RADIUS Start Packet Rates:
       Ascend-Data-Rate = 24000
       Ascend-Xmit-Rate = 52000

RADIUS Stop Packet Rates:
       Ascend-Xmit-Rate = 52000
       Ascend-Data-Rate = 24000

This feature has now been implemented, but is tested only on my system.  Can you confirm this fixes it.  Note that for true ISDN calls, it will still be necessary to disable echo cancellation.
