[OpenSIPS-Users] Problem with add_rr_param() in v2.4.7

[John Quick]

Hi Bogdan,

The only things that are unusual are:
 1) transport protocol conversion between TLS and UDP so it requires double RR's.
 2) it must use FQDN instead of IP address in the Record Route headers for the TLS interface

The script adds two RR headers like this:

record_route_preset("<addr-as-FQDN>:5061;transport=tls", "<addr-as-IP>:5060");
add_rr_param(";r2=on");

There is also one more call to add_rr_param() after those two lines, but none of the parameters is added.

For calls going in the other direction:
record_route_preset("<addr-as-IP>:5060", "<addr-as-FQDN>:5061;transport=tls");
add_rr_param(";r2=on");

When testing with v2.4.7, the listen statements were like this:
auto_aliases=no
alias=udp:<addr-as-FQDN>:5060
alias=tls:<addr-as-FQDN>:5061
listen=udp:<addr-as-IP>:5060
listen=tls:<addr-as-IP>:5061

One idea I had is that it might work to use record_route() instead of record_route_preset() provided I changed the second listen statement to this:
listen=tls:<addr-as-IP>:5061 AS <addr-as-FQDN>:5061

...but I haven't tested to see if the fault only happens with record_route_preset() and not with record_route().

Hi John,

So you say you experience a regression between 2.4.6 and 2.4.7.... Any particularities in terms of how you do the record_routing() and add_rr_param(), like sequence, other msg changes or signaling ?

Any simple way to reproduce the issue?
