[asterisk-users] BRI line issue on third call

I've been having a problem for some time now that I can't figure out how
to solve it.
On a PTP BRI ISDN line, if I have both channels in use and I place a
third call from the outside, I'm not getting a busy tone like I should.
Instead I get a congestion tone, as if the line was not working/didn't
Currently I'm using mISDN 1_1_9.1 and Asterisk 1.4.35 with an OpenVox
B400P and I've tried all possible combinations of PTP/PTMP and with or
without the termination jumper on the card.
I've also tried to make it work since mISDN 1_1_8 and Asterisk 1.4.18.
This is the message I get in Asterisk when the third call tries to come in:
P[ 4] channel with stid:10020400 in use!
P[ 4] channel with stid:10010400 in use!
P[ 4] There is no free channel on port (4)
P[ 4] --> !! lib: No free channel!
P[ 4] I SEND:RELEASE_COMPLETE oad: dad: pid:0
P[ 4] --> channel:0 mode:TE cause:0 ocause:0 rad: cad:
P[ 4] --> info_dad: onumplan:0 dnumplan:0 rnumplan:0 cpnnumplan:0
P[ 4] --> we have already send Release_complete

Does anyone have any idea what can be causing this?
Thanks in advance,
