Hi,
I'm new in Cisco. I have 2811 router with VWIC-1MFT-E1 and I want to connect 2 different network to it (data & voice).
eg.
Data&Voice----->2811---->E1----->2811---->Data&Voice
my question is :
At first I'm connect the VWIC-1MFT-E1 to Pbx. The system is working fine. But when I'm connect the 10/100 Fast Ethernet ports to Data network, the Pbx start going intermittent. Can you help me how to solve this ? Is my config is wrong ?

Have you set clock source internal for the PBX E1 ?

Under controller E1 0/2/0 configure:
clock source internal
04-21-2009 03:02 AM
I've done the config but still can't. Do I need to config both router ? And is my previous config is correct ?

Send a corrected network diagram because the one aboe doesn't really make sense.

You cannot have the same destination-pattern .... for both pots and voip DP. Configure them correctly accordingly to the numbers in use.
You also need to configure incoming called-number for both DPs.
04-23-2009 05:51 PM
Configured already but still can't. My config :
dial-peer voice 2 voip
description ROUTER_BKE-TP to ROUTER_BRT-RCC
destination-pattern 16..
dial-peer voice 2015 pots
description ROUTER_BKE-TP to PBX_BKE-TP
destination-pattern 10..
Sorry, but is it because of the pri-group timeslots below ? It should be 32 ts right ?
controller E1 0/2/0
clock source internal
pri-group timeslots 1-12,16
tq

According to the pbx vendor the destination pattern should be :
destination pattern ....
as the pbx will forward the number to router.
04-25-2009 01:15 AM
Let the PBX vendor care about the PBX only,
You need a proper configuation of the routers or nothing will work. I recommend you hire a reputable partner for that.
04-29-2009 06:43 AM
But when I try to enter the
command "pri-group timeslots 1-31" under the E1 controller I
get this error:
% Not enough DSP resources available to configure pri-group on controller E1 0/0/0
% The remaining dsp resources are enough for 0 time slots.
% For current codec complexity, 2 extra dsp(s) are required to create this voice port.
Is it true that's why my network is intermittent.
