Hi,


Currently i have a Cisco 2851 router with 1 VWIC-1MFT-E1 installed and just added another VWIC-1MFT-E1.


Please advise on the config on how should I add both E1 card to the same group.(the second ISDN30 is a slave ISDN bt Telco).


The changes config will be as follows:


controller E1 0/1/0

pri-group timeslots 1-31 service mgcp

!

controller E1 0/2/0

pri-group timeslots 1-31 service mgcp

!

interface Serial0/1/0:15

no ip address

isdn switch-type primary-net5

isdn incoming-voice voice

isdn bind-l3 ccm-manager

no cdp enable


interface Serial0/2/0:15

no ip address

isdn switch-type primary-net5

isdn incoming-voice voice

isdn bind-l3 ccm-manager

no cdp enable


Is this correct ? Thanks in Advance

Yes, assuming you're running MGCP, this is correct. In Callmanager, you will need to create a Route Group for each E1 and then create a Route List that includes both Route Groups. Then assign this Route List to Route Patterns.


Hope this helps. If so, please rate the post.

Hi Brandon,


Thanks for your prompt reply.


Now I faced some error


5vgw1(config-controller)#pri-group timeslots 1-31 service mgcp

% Not enough DSP resources available to configure pri-group on controller E1 0/2

/0

% The remaining dsp resources are enough for 18 time slots.

% For current codec complexity, 1 extra dsp(s) are required to create this voice

port.


Is that mean that i need 2 purchase DSP module ?


Pls advise as i am new in VoIP.


Thanks

Hi Brandon,


I managed to find out the the current 2851 router has only PVDM2-48 installed.


I may need 2 purchase PVDM2-16 to support 2 E1 card.


Is it correct ? I do not think i need 2 purchase any license as it route to the Call Manager


Appreciated your kind reply.

Hi Norman,


Yes, you are correct here. You are short 12 DSP resources to complete the 30 channel E1. You would need to order at least the part you suggested PVDM2-16 (48 + 16 = 64 channels). There are no additional licenses required. Here is a good doc;

Hope this helps!
