[SR-Users] Text Operations on a Message

[AliReza Khoshgoftar Monfared]

Thanks very much Alex.
You are right. In general kamailio does not offer much functionality of a
general purpose language.
The other option for the task that I found was "s.rm" transformation.
Although it works the other way :) you need to match what needs to be
removed :)

Now a general question ( or request for a word of advice :) ): if you have
ultimate flexibility and want to send an integer from one proxy to another.
What functions ( modules ) are the best to append and recover it? ( i don't
care where it is appended, body or header, etc )
