cipc inside a vm

by ⋅ Leave a Comment

CIPC is a great tool for troubleshooting voice, but it kind of requires a sound card to work, which a VM doesn’t provide and sometimes that’s all you have. To get magic audio inside a VM that has no sound hardware, you can create a virtual sound card. It’s removed from the gui for some reason, but not that difficult. Just RDP to the VM and redirect the audio to your desktop!

Edit the .vmx file and add the following code: (it helps if you’re in notepad++ so the format is right)

sound.present = “TRUE”
sound.allowGuestConnectionControl = “FALSE”
sound.virtualDev = “hdaudio”
sound.fileName = “-1”
sound.autodetect = “TRUE”

application dial rules

by ⋅ Leave a Comment

The problem with dialing from Cisco Jabber is that contacts that are synced from Outlook and/or AD need to be dialed from both Jabber and Mobile phones.

Instead of adding a “9” or pstn prefix to your Outlook contacts or in Active Directory, CUCM can automatically prepend your PSTN prefix when dialing from Jabber.

First, add the application dial rules in CUCM under Call Routing, Dial Rules, Application Dial Rules – Notice “Number Begins With” is blank

Next, you’ll need to grab the file “cmterm-cupc-dialrule-wizard-0.1.cop.sgn” from the Jabber for Windows admin pack, upload to your CUCM cluster and restart tftp services.

sip redundancy

by ⋅ Leave a Comment

In CUCM, sip redundancy is provided by either route groups/route lists or srv records.
The only method for sip redundancy on CME systems are srv records.

==================================
ip host losangeles.domain.com 216.82.225.202
ip host newyork.domain.com 216.82.224.202

ip host _sip._udp.sipgroup.domain.com srv 1 50 5060 losangeles.domain.com
ip host _sip._udp.sipgroup.domain.com srv 2 50 5060 newyork.domain.com

ip domain lookup
ip name-server 10.3.0.1
ip domain name domain.com

sip-ua
sip-server dns:sipgroup.domain.com
================================

This example will use los angeles all the time unless unreachable, then use new york,
If I were to set both priorities to 1, they would load balance. The 50 is weight, so you could set 60/40 or whatever..
