Hi,

why are you calling record_route_advertised_address(..) on these replies or in-dialog requests? The record_route functions are usually used on initial dialog forming requests (INVITE, SUBSCRIBE etc..).

Cheers,

Henning

They occur when calling it on responses to the initial INVITE, for example 183 and 200 OK.

Hello,

are those messages printed during the processing of the initial INVITE or when handling requests within dialog (re-INVITE, BYE, ...).

Cheers,
Daniel

I am using record_route_advertised_address to insert a record route header with an SRV record. The header is added correctly and everything appears to be working fine however I get a CRITICAL log error when calling 

record_route_advertised_address('INTERNAL_SRV');

Any ideas? I'm considering using insert_hf() to manually add it and bypass whatever check is failing. Thoughts?

Thanks
