Cisco ISR 4331 - voice gateway configuration

[Marius33]

Hi everyone,

I am trying to expand my existing VoIP network that uses a CUCM 11.5  to another location using a newly bought CISCO isr4331/k9 but I've never configured an isr4331/k9 and don't know how to proper make use of it.

I need to install 80 Cisco 7821 at the new location and I also want to enable SRST so the phones can still call locally if isr4331/k9 loses connection to the CUCM.  

Can someone please explain some steps for me to follow, some tutorials or a list of commands that I need for the isr4331/k9.

Thank you for your help!

If so you cannot have the E1 configured to be controlled by MGCP. That’s a CM control protocol. You need to configure the E1 port to be controlled by the gateway (router) itself. You do that by using dial peers. The default protocol is H323, but as that’s being deprecated by Cisco your better of to use SIP as the protocol on your dial peers.

Hu Marius,

Please add the following command:

voice service voip

sip

min-se 3600
session refresh
registrar server
asymmetric payload full
early-offer forced
midcall-signaling passthru

Try another call an attach the new debug

Thanks

Still unknown number.

Ok.

Please send the output of a show inventory and show voice register global

Also a show voice register pool 4 and 9 would be useful.

Thanks

Regards

Carlo
