VG450 running SIP and management from CUCM

[kbeaton]

We have a VG450 running SIP.
Call Manager version 12.5.1.18901-1
VG 450 Firmware Version 17.09.05a

I've had a support engineer helping me get this VG online and set up.

Can the VG450 be managed from Call Manager?
Is Call Manager supposed to configure both the voice-port and the dial-peer?
Or do these still need to be configured from the CLI?

[Jaime Valencia]

If you're running SIP you need to configure CUCM and the VG independently, CUCM is not going to push any configuration to it, you'll configure the VG with whatever you need via CLI

[kbeaton]

So even though the VG450 running SIP will register with Call Manager, Call Manager can't manage the VG450?

To enable the auto-configuration, use the ccm-manager sipana auto-config local command. To get the XML configuration file, use the ccm-manager config server command to download the configuration file from the CUCM TFTP server. Configurations are needed on both CUCM and voice gateway. CUCM needs to be configured first, then those configurations can be pushed to the voice gateway.

!
ccm-manager sipana auto-config local GigabitEthernetx/y/z
!
ccm-manager config server 172.xx.0.0
!

Note- Auto-Config only adds the dialpeers for each endpoint configured on CUCM. All other required SIP CLI commands need to be added.

Here is the document that has more detailed instructions:

This command is not relevant to a SIP config. The OP would need to use MGCP or SCCP if they expect CUCM to provision most of the voice functionality on the VG.

Hi @Jonathan Schulenberg, can you please elaborate how these commands are not relevant to SIP configuration? The document clearly specifies the Auto Configuration section. Am i missing something?

I thought I would share what I'm seeing
I have two servers I'm trying to get configured

My apologies @Vaijanath Sonvane. I overlooked the sipana keyword after ccm-manager and assumed MGCP/SCCP. Thanks for sharing this!

[kbeaton]

Hi Vaijanath, do you know if running "no dsapp line" and "dsapp line" to get the VG to synchronize with Call Manager?

I'm being told running these commands is the only way to get synchronization to happen?
