Hello,

maybe the R-URI (address in the first line) is coming with a local domain/ip, and then strict routing is done, meaning that next route header is moved to R-URI, from where it can be overwritten by other config actions.

Anyhow, set debug=3 and what the messages printed by rr module and core when executing loose_route(), it shoud show if the URI in the route or R-URI is matching myself.

Be also, you don't have any remove_hf("Route") executed by mistake (you can use debugger module with cfgtrace enabled to check what actions are executed).

Cheers, Daniel

Hi Daniel,

Thanks for the reply.

I don’t see the CARRIER_IP listed as an alias, and I have only 1 domain listed and that’s local. I also toggled the register_myself parameter and it is still removing the none local CARRIER_IP.

The route header containing the CARRIER_IP doesn’t contain a from tag, apart from that it looks normal and I cant fine any reference to it locally.

I haven’t seen this before, however this is my first time implementing things in Azure and on centos 7. Its only on outbound calls as well, what other steps do you suggest if any?

Thanks for the reply.

Jon

Hello,

that can happen if you have CARRIER_IP as value for alias global parameter or inside the domain module records with register_myself modparam enabled. Can you chack if any of those cases happens?

Hi Guys,

 

Sorry if this is too generic or silly a question but I am testing

kamailio 5.3.5 within Azure and its behind NAT.

 

I am having an issue with passing an ACK from our internal side
back out to

the carrier side and it appears having run loose_route a none
local route-header is

consistently being removed by kamailio at this point.

 

ie Route: <sip:CARRIER_IP;lr> <sip:CARRIER_IP;lr>

 

Is this normal or configuration related?

 

As I am unsure within what scenario I would remove a route header
which doesnt contain the local

Proxy IP.

 

Please can someone advise?

 

Many thanks

 

Jon
