Hi! Please help me to figure out how to use "@select" or "$sel" in routes.
For example: there is a sip message at the entrance of kamailo. This message contains an authorization header.
Authorization: Digest username="oleg.pershin", realm="178.62.221.112", nonce="VMT1cVTE9EVT/6/MLuDZR8dA4g1Mfir4", uri="sip:178.62.221.112", response="6eb5427433ef0b51832829f9fd4340ea", algorithm=MD5
Authentication Scheme: Digest username="oleg.pershin" realm="178.62.220.111" nonce="VMT1cVTE9EVT/6/MLuDZR7dA4g1Mfir4" uri="sip:178.62.220.111" response="6eb5327433ef0b51832829f9fd4340ea" algorithm=MD5
So I want to get a value from the "nonce" with "@select" or "$sel" functions .
How will it look like?
Best regards, Oleg Pershin.
