UC500 Hunt Group

[richb1971]

Hi folks,

Got UC500 & 520 switch. Have created Hunt Groups and added members but get Busy when I dial HGPN. I also intermittently get Busy when dialling a DN which is free??

Any ideas?

Which exact IOS are you running ?

[richb1971]

12.4(11)XW6-ADV-IP-SERV-CRYPTO

[paolo bevilacqua]

That should be fine (although latest is XW8).

Please send ephone-hunt, ephone, ephone-dn config, pls mention which phone loads you're running on the phones.

[richb1971]

This issue happens on most phones. I'm onsite now so your help is very much appreciated. I'm considering upgrading to uc500-advipservicesk9-mz.124-20.T.bin. What do you think?

Hi, config seems fine.

There's an "SR4" release, slightly newer for the 7941. Try doing a factory reset to the problematic phones, but make sure you've all the FW files in flash an configured with "tftp-server".

I recommend you only use XW train for UC500.

Please remember to rate useful posts.

Hi- found it!

The Config 'ASSistant' had created 2 phones with same number but it doesn't show this in the Config Assistant (only CLI). I've removed the phantom ones and all's well.

Thanks for help

Rich.

[paolo bevilacqua]

Good to know, thanks for sharing.

Another documented reason to trust CLI only to get good results using Cisco gear :)

[richb1971]

Doesn't look like it can do Broadcast Hunt Groups! Surely????!!!

Rich

[paolo bevilacqua]

Yes, with CME 4.3 (XZ IOS), if you're brave enough to try that.

EDIT - unfortunately CME 4.3 is not available yet for the UC500.

Note 1: Generally blast calling cause more problems than what it solves.

Note 2: most situations can be resolved with the Hlog softkey. People that is not avaialble to answer pushes that and you can also have auto-logout if you want.

Note 3: There are alternatives to parallel hunt groups even without XZ IOS. Ask when in need.

[richb1971]

OK so I can scratch 4.3 for UC500-thanks for saving me time trawling.

Note 3 sounds promising. Can you help?

That is shared lines, however there drawbacks mainly related to additional calls coming in, that force you to daisy-chain DNs with CFB.

Basically you assign the same DN to multiple phones making it a shared line.

Then if you're really adventurous you can try a script that I wrote for blast calling:

All in all is better to spend some time to educate end users to the use of HLog - it worked for so so fare even when they were crying for blast calling.

[richb1971]

Hi-thanks again. So using shared line will only allow 1 call in at once, is that right?

[paolo bevilacqua · Accepted solution]

The thing is that a second call to the same shared DN will go only to the ephone that took the first one.

The workaround is to configure a chain of DNs large enough to accommodate the number of calls that you anticipate can be received, and place said DNs in overlay on a single button with the "c" keyword.

All that is confusing enough so in CME 4.3 Cisco introduced parallel hunt-groups, octo-line DNs and removed the stickiness of subsequent calls to the engaged ephone.

[richb1971]

Got it working using hunt stops and lots of extra ephone-dn's. What a pain! UC500 does not support Broadcast Hunt Groups???!!! Pretty poor that.

Thanks for your replies.
