[Asterisk-Users] chan_capi and AVM FritzCard PCI

[Christian Heindl]

Hello everybody,

i´ve set up asterisk with an avm fritzcard pci, which is directly
connected to my s0-bus from my mainline; so on this side i get incoming
calls.
On the otherside there are several sip-phones, which are to answer the
incoming calls.

This set up works quite well, when a call comes in. The problem starts
when there comes a second (parallel) call on the s0-bus. Asterisk
recognizes this call and dials for the sip-phones. They are ringing and
if i answer the call with a second sip-phone, the audio from the first
call isn´t transmitted anymore. The connection of the first call doesn´t
break, but the audio is broken.

I´m using Asterisk 1.0.9 in combination with chan_capi-cm 0.6 from
sourceforge.net.

Does anyone had the same problem? Is there any solutions to this?


cheers,
christian
