Shah Posted January 20, 2021 Report Posted January 20, 2021 Hi all, Is there a guide / how to on setting up Kazoo in Azure? If not, does anyone want to help me create one for the community? If I'm building the environment in Azure, I might as well share the lessons learnt. I heard that as the public IP is not visible inside the VM, the out of the box config does not work? Any inputs are welcome. Cheers

shamesaaron Posted January 20, 2021 Report Posted January 20, 2021 I don't think he is looking for alternatives to Azure. He wants to know how to get Kazoo to work within Azure Cloud. The only issue I can think of is Kamailio not being able to bind to the external IP. Does anyone have config examples of how to use Kamailio when it cannot bind to the external IP? I know someone had got Kazoo working within Docker which would have required a similar type of config.

I know @Shah personally, and I know that he is a Microsoft partner and works with Microsoft solutions on a daily basis. If your DM doesn't involve getting Kazoo working in Azure, it will not be useful. If it is about getting Kazoo working in Azure, please do share for the community.
Meat Posted January 20, 2021 Report Posted January 20, 2021 The below works in AWS. I haven't worked much with Azure's networking environment, but I can't imagine (well, I can, it's Microsoft) that the DNAT / SNAT workings are too different. Assign PUB IP to instance/interface, then just change the below configs in Kamailio and Freeswitch. If you're using an all-in-one, then you'll just need one PUB. I've got a clustered setup going with my Kama and FS instances separate. On Freeswitch - Remember FS trunks directly out of the cluster. It does not route out back through Kamailio. nano /etc/kazoo/freeswitch/sip_profiles/sipinterface_1.xml Set <param name="ext-rtp-ip" value="auto"/> to <param name="ext-rtp-ip" value="x.x.x.x."/> (x.x.x.x is the external IP you have assigned to this instance) Set <param name="local-network-acl" value="localnet.auto"/> to <param name="local-network-acl" value="NOPE"/> # “NOPE” doesn't matter, just not localnet.auto On Kamailio nano /etc/kazoo/kamailio/local.cfg Should be down at the bottom of the file. The advertise flag essentially tells Kamailio what to change the IP to when it detects NAT. listen=UDP_SIP advertise x.x.x.x:5060 listen=TCP_SIP advertise x.x.x.x:5060 (where x.x.x.x is your public IP address you assigned) I believe that's it. Hopefully that'll help.
Shah Posted January 20, 2021 Author Report Posted January 20, 2021 Thanks @Meat, that does look promising, I'll try it out and share for everyone to know. @fmateo05, thanks for the DM and the tip, for now I'm not evaluating other cloud providers, but I'll keep upcloud in mind.
RuhNet Posted January 23, 2021 Report Posted January 23, 2021 You might find this link helpful. Although it's for AWS, the same config (at least mostly) would apply to Azure. https://github.com/OpenTelecom/kazoo-install-guide

Hopefully that'll help. Can confirm, applied these settings to a sandbox deployment without a bindable external IP and everything worked perfect.
tomas_ Posted May 12, 2021 Report Posted May 12, 2021 (edited) I can also confirm this, in Amazon EC2. But I only needed to change the Kamailio config. Correction; I also needed to add external/public ip to FreeSWITCH server at ext-rtp-ip, otherwise the sound didn't work. Br Tomas Edited May 17, 2021 by tomas_ (see edit history)
tomas_ Posted November 25, 2021 Report Posted November 25, 2021 Hi again! I have the same issue again, now with another carrier that connects via VPN (AWS Direct Connect) and not through the public internet. They can't reach our external IP, so it's not useful here. What IP should I use in the configs? Br Tomas
fmateo05 Posted November 27, 2021 Report Posted November 27, 2021 I believe you can use the internal kamailio IP instead
tomas_ Posted November 30, 2021 Report Posted November 30, 2021 (edited) Thanks! Yes, that seems to work, but only for the traffic to/from the carrier. SIP clients dosen't have any sound, because the internal IP isn't reachable from the outside. I will start a new thread with that issue: https://forums.2600hz.com/forums/topic/12691-dual-media-gw-address-signalling Br Tomas Edited December 2, 2021 by tomas_ (see edit history)
