Hello,

yesterday afternoon I pushed an alternative for allowing setting the address and port in local Via headers using XAVP, see:

  - https://www.kamailio.org/wiki/cookbooks/devel/core#xavp_via_fields

I didn't have the time to do any tests, but was in master before freezing code for 5.2.x series, so it will be in the next major release. Test and if there is any bug, report and it will be fixed.

I also looked at extending the set_advertised_address(), but it actually uses pointers to some static values available at kamailio startup, so making that dynamic would have been more complex to do in a short time.

Cheers,
Daniel

Thanks for the replies Daniel and Henning!

The problem with the listen address is that it can't be set at run time per call, for example, after reading the value from the DB.... And also it is way too dirty to use the set_advertised_address with a static string value....

Long story short, we have a weird telco setup which only allows the SIP trunk to terminate in their own network, which then puts my Kamailio behind a NAT box only for them.  And because they are the biggest carrier in that country, we will have to workaround the issue.....

Kamailio itself has only one network interface to communicate with everyone (other provider and extensions), so I was trying to actually only set the advertise address before sending call to this specific telco. For calls to anyone else I would not set the advertise address. Looks simple, but seems not that easy to implement.....

Cheers,

Hello,

the pseudo-variable is read only.

The recommended way would be to use listen with advertise, like:

listen=udp:1.2.3.4:5060 advertise 5.6.7.8:5060

That will take care of both Via and Record-Route headers as well as
matching myself, no need to do other stuff in route blocks. Doesn't work
for you?

Cheers,
Daniel
