asterisk users - Jul 2004 - * and Innovaphone

Hello,

I think I have the same problem as Martin Bene mentioned in
http://lists.digium.com/pipermail/asterisk-users/2004-January/034521.html
Since I found no further information about this I'd like to ask wether 
you know what the reason for this problem is and how one can get around 
this.


* is registered to the innovaphone gatekeeper.
Trunk connection is done with an AVM-B1 and chan_capi.

Torsten Krueger

Call signalling works fine, but in H323-Trace the following is shown:

I've since spent some time debugging the problem:

The innovaphone gatekeeper hands out a bandwidth allocation of 8kbit on
registration; I haven't found any way to deactivate or configure this
limit.

Two possible workarounds:

* Don't have asterisk register any extensions with the gatekeeper

* Or, as an utterly ugly workaround, I've hacked the openh323 libs to
ignore the bandwidth limit and proceed andway. Seems to work OK.

Bye, Martin
