Hello Friends
I have two voice gateway,Both had the VWIC3-2MFT-T1/E1 card. And now we also have three E1 line. Who can tell me how do I implement equipment redundancy and Line redundancy ?How do I do on the gateway configuration?
Best Regards

Hi,
I was writing from my phone app so was difficult to explain in detail. Now I am back.
Create single RG with both H323 gateways assigned (GW01 & GW02). Use distribution algorithm as circular to load balance.
For VG1 which has two E1 lines, you can configure a trunk group and make you hunting algorithm as circular. Then use this huntgroup for your outgoing dialpeer.
Now regarding your DIDs, it depends on your telco. If your telco is extending the same range of DID to all lines then all your DIDs are available during failure of any line for inbound calls. However, if your have different blocks of DIDs locked to different lines, some of the DIDs won't be available depending on the failed line.
For outgoing calls, they will always work, however, the caller ID might be different depending on what your telco is excepting as caller ID

Hi,
The configuration for trunk groups in PRI can be achieved as below.
controller E1 0/0/0
pri-group timeslots 1-3,16
trunk-group test timeslots 1-2
Also, if you have two dialpeers with same patterns and preference, they will load balance the calls randomly (by default). You can change this using dial-peer hunt command

Hello,
Whats your IP Telephony Solution? CUCM? CME?
Take a look on this dicussion i think this fits to your situation

HI Leonardo Santana
I use CUCM,I just want to know What kinds of way can implement equipment redundancy and Line redundancy.Can i made my VG01 and VG02 in a Active Active Mode.How do I achieve the best use of E1 lines.

Hi,
You can add your gateways to cucm using sip, h323 or mgcp. Then create two route lists, one for each gateway, and use circular selection. This will load balance calls across both E1

Yeah,I had finish h323 config and I had config RG01 and RG02 with Distribution Algorithm as Circular,
RL01 Selected Devices RG01 and RG02
RL02 Selected Devices RG02 and RG01
I know E1 has different DID so I don't know what need i pay attention to for my voice gateway config,If primary VG01 is down ,All my DID is still available?

HI friend
I think i had understand what you said,About DID I am clear now.
About VG
1.when i configure a trunk group ,it noted this error.

Hi,
Can you describe the topology?

Hi friend
As the picture shows,I had two voice gateway and three E1 lines,Gateway use h323 to CUCM Cluster,IPphone use sip or sccp to CUCM,How can i implement equipment redundancy and Line redundancy,i want to made best use of my voice gateway and E1 lines.I want to know how do I config my voice gateway.
