Hi everyone,
I need your advice. I am extracting a SIP Body message from a User Agent Client using the regex as such "$var(calling_party)= $(var(body){re.subst,/.*Calling-party:\s*sip:(+[0-9]+)@.*/\1/});"
And I tried to log it as "xlog("L_INFO", "Extracted number 1: $var(calling_party) <><><>\n");"
However, the output in my logs is only showing as below, where I cannot see any value after my variables. "1(6) INFO: {1 10 SUBSCRIBE 5017ae21204c72a3} <script>: Extracted number 1: +6512345678"
I suspect this is the reason why when I tried to use this variable in a redis_cmd, it returns as null as the variable may have impacted the command input to Redis.
I tried to change the $var(calling_party)="+6512345678" and it is working perfectly fine
Best regards, Timothy

maybe you can give and example of such body so we can try to suggest solutions. Looking at the regex and not knowing the input is not easy to guess.
Cheers, Daniel
Hey Daniel,
This is the expected body to be sent by the User Agent Client
Calling-party: sip:+46761153802@telco1.com;user=phone Called-party: sip:+46701234567@telco2.com;user=phone
The goal is to extract the phone number and store it as a variable which will be used to query to Redis
Best regards, Timothy
