I've an cisco 3640 with a VWIC-2MFT-E1 network module. Can anybody tell me why i cant configure any voice-port? without able to configure voice-port, i cant assign any port for my "dial-peer voice xx pots". Anybody has any solution?
what im trying to do is sending voice data traffic to 192.168.10.1

controller E1 1/0
framing NO-CRC4
clock source line primary
channel-group 0 timeslots 1-31

interface Serial1/0:0
bandwidth 2048
ip address 192.168.10.2 255.255.255.252
ip mtu 300
encapsulation ppp
no ip route-cache

Re: cisco 3640 cant configure voice-ports

There is no support for the VWIC-2MFT-E1 on a 3600.  Support is available for the VWIC-2MFT-E1-DI, but with one serial channel group.

Re: cisco 3640 cant configure voice-ports

Thanks for the reply. After reading the data sheet, i got a clearer understanding. It says i need either NM-1FE2W, NM-1FE1R2W, NM-2FE2W to get one serial channel group for my VWIC-2MFT-E1. Am i right? Meaning to say, if i get one of those WIC, im able to create voice ports?

Another question, my 3640 has a WIC which is in used for WAN and a 12 port vlan-switch network module, i understand i need (NM-1FE2W, NM-1FE1R2W, NM-2FE2W) to be able to config voice ports on VWIC-2MFT-E1. Is there any other way to configure to send voice traffic out without voice-port configuration?

That is incorrect. See: http://www.cisco.com/en/US/products/hw/routers/ps259/products_tech_note09186a00800e73f6.shtml

table "Cisco ICS 7750, 36xx, 37xx, and 38xx Platforms Matrix"

In any case, the 3600 is too old for effiencient voip, but use something newer instead.

For E1 PRI voice configuration, we will need to configure "pri-group" under the E1 controller :

Please refer to the following URL :

Please note that 3600 is End of Life :

Re: cisco 3640 cant configure voice-ports

I've only got this from my controller E1

Vertigo(config-controller)#?

Controller configuration commands:

  channel-group     Specify the timeslots to channel-group mapping for an

                    interface

  clock             Specify the clock source for a DS1 link

  default           Set a command to its defaults

  description       Controller specific description

  detect            Enable detection of loopback request

  exit              Exit from controller configuration mode

  framing           Specify the type of Framing on a E1 link

  guard-timer       Guard timer (0-20) for xcsp calls - timer duration and

                    accept/reject on expiry

  help              Description of the interactive help system

  line-termination  Specify the line termination for E1

  linecode          Specify the line encoding method for a E1 link

  loopback          Put the entire E1 line into loopback

  mode              Configure the controller mode

  no                Negate a command or set its defaults

  shutdown          Shut down a E1 link (send Blue Alarm)

  tdm-group         Configure DS0 group for TDM

Do i need DSP for the voice-ports? Please guide me on what more module i need to get. Thanks!!

Re: cisco 3640 cant configure voice-ports

Yes, we will need DSP(s) to enable voice functionality.

Please use NM-HDV, VWIC-2MFT-E1 and PVDM modules for E1 PRI in Cisco 3640 :

http://www.cisco.com/en/US/partner/tech/tk652/tk701/technologies_tech_note09186a00800b65d6.shtml

Also, if this router is for production network please note that Cisco 3640 is End of Life / Support. For production use, please consider ISR (18xx/28xx/38xx) or ISR-G2 (19xx/29xx/39xx).

Re: cisco 3640 cant configure voice-ports

I have no idea with what you are designing or what you are achieving but I can tell you this:  I will never, ever, design  voice/fax systems built around a 3600:  It's too slow for current VoIP and hardware support is very difficult.

Supporting a legacy system would be financially un-sound.
