Do I need an special configuration to use np60 module to an E1 for VOIP?

You acn refer the following document for the configuration. No special configuration is needed for NP 60 module

Cisco ATA 186 Problem

Hi. I have some problems with VoIP
I use csico186 to connect telephones to router. As you know I can connect two telephones lines to the same Cisco ATA 186. So,
these two lines will have the same IP.
The problem:
Line 1: 222 333 888
Line 2: 222 333 999
When any body dial the first number the call will received in the first line or the second line randomly

Have the destination pattern being configured as wildcard or an exact match? Hope the wild card is not matching to both the
numbers. The dial peers have to be configured separately for both the destination patterns. And the voice ports have to be
configured under respective dial peer.

Does anybody know if Caller ID Name is supported with the AS5350 Sip gateway terminating PRI to a Class 5 Switch. If so,
which IOS, and how is it configured? Thanks

AS 5350 supports caller ID information. Use debug isdn q931 to troubleshoot if you face any problems.

Quality of service for prioritizing Voice by limiting Bandwidth

Dear Members,
I am trying to give priority to voice over other traffic by setting up a below test bed in my lab.
Voice receiver
Background receiver ---- Ethernet E0---- Router 1------Ethernet E 1----- Background traffic generator
Voice generator
Here Voice receiver, Background receiver and router 1鈥檚 EO interface forms one Ethernet segment.
(Actually I am using three routers. But for easy debugging presently I am working with one router)
Router 1鈥檚 E1 interface, Voice generator and background traffic generator form other Ethernet LAN.
I am limiting bandwidth of router E0 interface to 48kbps by below commands:
***********
I am sniffing at the interface E0 using Ethereal sniffer-protocol analyzer. But I am unable to get better results for voice
application over background traffic. For both Testing without QoS and with QoS I am getting the same results.
FOR EVERY VOICE PACKET I GET ONE BACKGROUND PACKET- SAME RESULTS FOR BOTH WITH AND WITHOUT QOS DEPLOYED
***********
The voice application is generating at 32 kbps with packet size frame size of 876 bytes.
It uses UDP port no 60600. It uses TCP port# 8896 for connection activeness. I am using these details in my QoS
configurations.
For initial testing, I am also generating background traffic also with 32kbps rate and frame size of 876 bytes.
Since total net traffic voice + background = 32 + 32 = 64 Kbps, so I am redUCing the bandwidth of the interface using 鈥榯
raffic shape鈥?and 鈥榬ate-limit鈥?commands.
Router 1:
Option 1:
Conf t
int e 0
rate-limit output 48000 6000 6000 conform-action transmit exceed-action drop
Option 2:
Conf t
int e 0
traffic-shape rate 48000 6000 6000 1000
I think with the above configuration, all traffic above 48000 bps are dropped.
So there are good chances that 24000 bps of both voice and data are sent, and remaining s 8000bps for both voice and
background are dropped. So, therefore QoS does not come into picture because now total traffic is 48 but NOW actual interface
bandwidth is 10 Mbps after the 鈥榬ate-limit鈥?or 鈥榯raffic-shape鈥?phase.
IS THERE OTHER WAY TO REDUCE THE BANDWIDTH OF THE ETHERnet
InTERFACE.?
