Be aware that r-uri (request uri, represented by $ru as var) it is itself a
branch. Also $du (outbound proxy - destination uri) is associated with the $ru
branch.
In the config snippet, you assign values to $du, that means you set the
destination address for the branch of r-uri ($ru). because you only use append
branch, you don't change the r-uri branch and that stays as extra branch with
latest $du you set.
What you should do:
- if $var(i)==0 (the first row of the result) - set the $ru to the contact and
the $du to received value
- if $var(i)!=0 (the next rows of the result) - do append_branch() with the
contact and set the $(branch(dst_uri)[-1]) to received value
As a suggestion, you are using the string transformation to parse URI from
database in order to get domain part, etc... you better use the uri
transformation, because it is designed for this kind of need.
I am closing this here, such discussion has to be done on sr-users mailing
list, follow up there if you need further assitance.
