B800P NT problem

Hello grzegorz,
I am attempting to install BRI card(OpenVox B800P) with DAHDI driver(wcb4xxp), and I have googled a long time to find
whether it has a better solution for it, and I am so happy to see that you have written down its simple guide.I exactly
followed your simple guide that you had post before in this thread. But I still can not make it worked.

Here are my environments:

---

CentOS-5.3
Kernel-2.6.18-164.el5
asterisk-1.6.1.6
dahdi-linux-complete-2.3.0+2.3.0
libpri-1.4.10.2
OpenVox-B800P(the first port is spliting into two lines, I set the first one into NT mode,and others are TE mode)
patch- manual_te_nt.patch(which download from: http://www.openvox.cn/bbs/viewthread.php?tid=992 , and posted by Dmitry)

---

I make a fresh OS and yum install all the dependent packages, like bison,bison-devel,gnults-devel,gcc,gcc-c++, and so
on.
And download all the same versions of DAHDI-linux-complete-2.3.0+2.3.0, asterisk-1.6.1.6, libpri-1.4.10.2 from asterisk
official website: http://downloads.asterisk.org/pub/telephony/.

Completely plugs the card and start to compile and install those packages. Here are my installation steps:
A.Libpri: make-->make install --(no errors)

B.Patch file /usr/src/dahdi-linux-complete-2.3.0+2.3.0/linux/drivers/dahdi/wcb4xxp/base.c with this method:
patch p0 < manual_te_nt.patch

C.DAHDI: make-->make install-->make config --(no errors)

D.Edit and insert this line at the buttom of file /etc/modprobe.d/dahdi.conf(only this step is different from yours)
options wcb4xxp te_nt_override=0xFE

E.Start dahdi and automatically configure the channels with: modprobe dahdi-->modprobe wcb4xxp debug=16-->dahdi_scan--
>dahdi_genconf-->dahdi_cfg -vvvvvvvvv (no errors and all the channels are showing there)

Everything seems very good so far as!

F.Asterisk, ./configure-->make-->make install-->make samples --(no errors)

G.As you said before, NT mode with wcb4xxp only supports nt_ptp,and nt_ptmp is not work right now. So I set dahdi-
channels.conf like this:

---

; Span 1: B4/0/1 "B4XXP (PCI) Card 0 Span 1" (MASTER)
group=0,11
context=from-pstn
switchtype = euroisdn
signalling = bri_net
channel => 1-2
context = default
group = 63
; Span 2: B4/0/2 "B4XXP (PCI) Card 0 Span 2" RED
group=0,12
context=from-pstn
switchtype = euroisdn
signalling = bri_cpe
channel => 4-5
context = default
group = 63
; Span 3: B4/0/3 "B4XXP (PCI) Card 0 Span 3" RED
group=0,13
context=from-pstn
switchtype = euroisdn
signalling = bri_cpe
channel => 7-8
context = default
group = 63
; Span 4: B4/0/4 "B4XXP (PCI) Card 0 Span 4" RED
group=0,14
context=from-pstn
switchtype = euroisdn
signalling = bri_cpe
channel => 10-11
context = default
group = 63

---

and other spans 5,6,7,8 are the same as span 2.

H. After this modification, the dmesg information shows like this:

---

Base on this information,it seems that the patch is working, so far so good!

I. Start asterisk with asterisk -vvvvvvvvvvvvgc.and run command "pri show spans", but shows like this:
*CLI> pri show spans
PRI span 1/0: Provisioned, Down, Active
PRI span 2/0: Provisioned, In Alarm, Down, Active
PRI span 3/0: Provisioned, In Alarm, Down, Active
PRI span 4/0: Provisioned, In Alarm, Down, Active
PRI span 5/0: Provisioned, In Alarm, Down, Active
PRI span 6/0: Provisioned, In Alarm, Down, Active
PRI span 7/0: Provisioned, In Alarm, Down, Active
PRI span 8/0: Provisioned, In Alarm, Down, Active

I have plugged the ISDN phone into the first port,and LED is turn to green and not blinking,but when I offhook, nothing
dial tone there,and this channel is always under DOWN status.

J. But sometimes it sharply turn to UP status. Under that situation,I was attempting to make some calls from softphone
to it, but I can not hear any voice between them(softphone or ISDN phone) ---(please see my screenshot in attachment)


Therefore, here are my questions.
1.I am not sure whether I missing some other KEY steps, could you please let me know?
2.Did you make some other editions in your successful solution?
3.Could you please tell me how to set the value of parameter "signalling" in file dahdi-channels.conf?
4.Do you know someone else has made it worked? Or other suggestions?
5.How can I make it always under "UP" status?



Thanks in advance!

Hi

I was have the same problems with sound as you. I not resolved this jet.
I was used signaling net_ptp on 1 port and cpe_ptp on else ports.

In this moment I don't have time to end tests but I will try resolve this in future.

If you find something please write.

Regards
Grzegorz
