E1 PRI

[adamgibs7]

Hello,

I have a E1 link and i want to distribute as follows:

• 6 channels for contact center------what commands i have to configure on voice gateway any sample configuration please.
  
• How can i assign 6 No's DN to these 6 channels so that these channels should not be used by coporate users
  
• Whenever a call hits on a tollfree , ITSP will route to 6 channels now these 6 DN's must be routed to call agent inside i hope this can be done by line group,hunt group.hunt pilot configuration.Please correct me ????

Hi,

I think your requirement of  binding of channels through Toll-Free can be controlled by E1 Service Provider not at GW/CUCM.

regds,

Hello Aman.

That configuration will be done by ITSP

But also i have to reserve the channels from my end, if i am not wrong the trunk-group command can help me? but i am confuse about the configuration.How to reserve this 6 channels dedicated to these 6 Extension.

After the call lands on the 6 reserved channels than it shld be routed to agents sitting in internal lan I think it is possible

by hunt list??

I am not sure what i need is possible but i need expert advice.

What do you mean by "reserve"?

ISDN endpoints can (will, should) intelligently choose a Bearer Channel for each and every call.

Hi,

is there a range of DID numbers assigned to this particular E1?

Also, do you have a UCCX or UCCE? Or is it only CUCM?

Hello, Gergely,

I mean to say by reserve is that they should not be used by corporate 200 users,  for corporate i want to keep 24 channels and 6 for Contact Center, I am not sure that it can be done,that the reason i want experts advice.

yes i have a 200 DID

i have a UCCX 9.0 and CUCM 9.0

Thanks

Hi, alright, so what I suggest to do is to create two dial-peers.

- one dial-peer will handle the calls incoming to the call center. Use the max-conn command to restrict the number of connections to 6.

- the second dial-peer will handle the calls incoming to the rest of the numbers. Use the max-conn command again to restrict the number of connections to 24.

Use the same port (~ voice port = E1) on both the dial-peers.

If you have multiple E1's, then you can bundle them into one trunkgroup and use the trunkgroup identifier with your dial-peers.

Hello,

Still not clear,

The MAX command 6 can also catch non-contact center number, on dial-peer,

What we can do restrict the dial-peer can accept only ext 1001,1002,1003,1004,1005,1006, on dial-peer 1 and on dial-peer 2 everything is accepted.

Thanks

Hi,

well this is what the incoming called-number command is for

If the dial-peer hunt method is set to 0 (default), then it would use the longest match anyway.

dial-peer voice 91 pots

description ** CC **

! match incoming to 6316681001-6

incoming called-number 631668100[1-6]

max-conn 6

direct-inward-dial

dial-peer voice 92 pots

description ** everything else **

! match the whole DID range

incoming called-number 631668100.

max-conn 24

direct-inward-dial

Well dear,

very good explanation,

Is it need to do the hunting on the agent DN in CUCM whenever a calll is received on the CC DN's.

Thanks

[Gergely Szabo]

Hi,

you mean like searching for an agent? Yes. Dial-peers send the calls to the CUCM but you might want to use UCCX for routing calls to agents. UCCX gives you call scripting and queueing and reporting capabilities.

I mean, you can also set up a simple hunt group in CUCM if you don't need anything fancy, but if you already have UCCX, you should probably use it.

Hello

Thanks for all your prompt replies i appreciate, just help me for the below to understand

Usually an incoming call always hits to CUCM and then it is routed to uCCX,

I want to use it on CUCM and then the call should route to CCX,

Can you brief or correct me if the below is wrong.

line group ----al the agents DN

Hunt list will include line group

Hunt Pilot (4000) will include the Hunt list.

But i want to be more clear how this hunting happens, can you elaborate more

[Gergely Szabo]

Hi,

you don't need hunt groups and line groups and all that stuff if you use UCCX. Having a call center usually means a step further from hunt groups.

Talking about hunt groups: there's a hunt pilot (4000 for instance) mapped to a hunt group which includes a line group of extensions. The call always comes in to 4000 and then it's up to CUCM to pick the agent, based on the hunt group preferences (for instance, longest idle etc).

Again, if you want to use UCCX, you don't configure hunt groups (but you do configure triggers, applications, scripts, CSQ's, teams, etc).

If you don't want to use UCCX, you do configure hunt groups.

I can see you are fairly new to the topic, you might want to attend a training or dig deeper into the documentation website.

Hello,

Please bare with me.I am very new to IP telephony.

The call always comes in to 4000 and then it's up to CUCM to pick the agent,the hunt pilot can be any number.

• How it will come when there is no destiantion pattern for 4000
  

• what shld be the hunt pilot number if i configure a dial-peer for the ext 1001-6 as an incoming called number
  

Can you route me to the document where the call flow can understand for UCCX triggers

[Gergely Szabo]

OK, everybody needs to start somewhere.

4000 was an example only. You can configure anything. For instance, the above pair of dial-peers would allow you to configure 6 hunt pilots, 1001, 1002, 1003 - 1006

Then you can just add 6 hunt groups to each hunt pilots. Each hunt group would contain a line group. Each line group contains a set of extensions.

Notice I gave you the configuration for the inbound dial peers, but naturally, you will have to configure the outbound dial-peer(s), too.

This is a simple outbound dial-peer, using H.323 as the signalling protocol.

dial-peer voice 10 voip

description ** outbound dialpeer to CUCM **

destination-pattern 6316681...

! this matches the whole DID range

session-target ipv4:10.20.30.40

! the CUCM IP
