Any one have configed Cisco Router 3825 to work with ISDN E1 line and callmanager?

Can you share your config sample?

Thanks alot

Let me know which protocol you want to use?

H.323 or MGCP?

I use H323 protocol

On my router 3825 i use "NM-1CE1T1-PRI" module

This module support E1 and T1 line

I use command "card type E1", and i can see interface from 0-30, E1 port on module is port 1/1.

But after config channel 15, i didn't find command to config voice port 1/1:D

(with E1 module, voice port is config to receive incoming call, and place out going call)

May be have some different with module NM-1CE1T1-PRI

Any one can help, thanks

here's a sample config from a router running H323

isdn switch-type primary-net5

controller E1 0/2/0

framing NO-CRC4

pri-group timeslots 1-31

interface Serial0/2/0:15

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn incoming-voice voice

isdn send-alerting

isdn sending-complete

no cdp enable

voice-port 0/2/0:15

dial-peer voice 1 voip

destination-pattern

session target ipv4:

dtmf-relay h245-alphanumeric

I have configed ISDN E1 with AS5300

But with this module i did not see voice-port :15 to config

Do you see this problem before? May be line E1 down or i did not config right ?

I user NM-1CE1T1-PRI module, after change card type to E1, i see all channel 0-30 but can not see voice port :15

Hi, all

Any one configed module NM-1CE1T1-PRI for voice.

After i config controller on e1 interface, config linecode, framing, pri timeslot, I didn't see any "voice port"

I sure that linecode, framing, e1 line is ok, because i use this e1 line with AS5350 and all thing run well

May be have some problem with module NM-1CE1T1-PRI. Do this module support Voice??

Or have some problem in hardware?

Thanks for all help

Let me know your router is taking the pri group timeslots 1-31 command or not.If there is any lack of DSP resources it will show u

Plz check this

http://www.cisco.com/en/US/products/hw/modules/ps2797/products_data_sheet09186a0080189f95.html

I use line E1, after config

"controller E1 1/0

framing NO-CRC4

pri-group timeslots 1-31 "

I see interface serial 1/0:0-1/0:30

And I config interface serial1/0:15( d channel)

"interface Serial1/0:15

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn incoming-voice modem 64

no cdp enable

!"

But after that, i did not see any voice port while type "show run"

I use software Version 12.4(13b)

Any one can help??

Do you have network-clock-select command?

And I think you should have "incoming-voice voice" instead modem 64.

regards,

pk

You can try one more command in controller E1

'clock source still if it is not showing u can change the IOS to 12.4T

Thanks thomasarun

I upgraded new software, new version is:

"Cisco IOS Software, 3800 Software (C3825-IPVOICEK9-M), Version 12.4(4)T8, RELEASE SOFTWARE (fc3)"

"Cisco 3825 (revision 1.0) with 226304K/35840K bytes of memory.

Processor board ID FHK0949F0LM

2 Gigabit Ethernet interfaces

31 Serial interfaces

1 Channelized E1/PRI port

4 Voice FXO interfaces

8 Voice FXS interfaces

DRAM configuration is 64 bits wide with parity enabled.

479K bytes of NVRAM.

62720K bytes of ATA System CompactFlash (Read/Write)"

But after try each of: clock source external, line, external, voice port 1/0:D did not show (my E1 port is 1/0)

May be this module NM-1CE1T1-PRI have some different in configuration.

Any one can help?
