[OpenSIPS-Devel] OpenTelemetry in OpenSIPS 4.0

Hello,

Currently the opentelemetry module only populates the initial span with 
the incoming message SIP details - so indeed a bit hard to correlate 
across several SIP hops if a b2b or dialog topology hiding is used.

Please open a feature request under 
https://github.com/OpenSIPS/opensips/issues to also attach the outgoing 
full SIP message details.

Regards,

Vlad
