[SR-Users] KEMI, Lua external modules and nonblicking operations

[Daniel-Constantin Mierla]

Hello,

a blocking operation in configuration file or kemi script is blocking
the sip worker. If your http operation is not blocking, then it is not
going to block the sip worker in kamailio. If you want to keep the sip
request until the http response arrive, suspend the transaction, do the
http query and when the response arrives, resume the transaction. See
tmx module for t_suspend()/t_continue().

Cheers,
Daniel
