Problems with B400P

what you mean by that? you have to check the cable and pins with your providers.

I want to set my ports of my B400p on point to multipoint mode. Because i have mutiple ISDN.

hello:
you can set that to PTMP mode in misdn.conf:
<port mode="te" link="ptmp">1</port>.
please refer this:

We use Elastix, and its reloading the old defaults every time when i change it.

Hello,
What do you mean"We use Elastix, and its reloading the old defaults every time when i change it."?
Please give more descriptions about it.

Have you done as James said on the previous post?

When i do asterisk -r

misdn show port 1
misdn show port 2
misdn show port 3
misdn show port 4

BEGIN STACK_LIST:
* Port 1 Type TE Prot. PTP L2Link DOWN L1Link:DOWN Blocked:0 Debug:0
elastix*CLI> misdn show port 2
BEGIN STACK_LIST:
* Port 2 Type TE Prot. PMP L2Link DOWN L1Link:DOWN Blocked:0 Debug:0
elastix*CLI> misdn show port 3
BEGIN STACK_LIST:
* Port 3 Type TE Prot. PMP L2Link DOWN L1Link:DOWN Blocked:0 Debug:0
elastix*CLI> misdn show port 4
BEGIN STACK_LIST:
* Port 4 Type TE Prot. PTP L2Link DOWN L1Link:DOWN Blocked:0 Debug:0


So its good now.

Port 2 and 3 are set to PMP now.
