[OpenSER-Users] Re: [Serusers] enum_query from failure route

[Bogdan-Andrei Iancu]

Hi Andreas,

as time the functions you are using are safe to be used in failure 
route, there is no problem doing that...:)

JF, regarding the "enum" functions in failure_route: the reason for not 
being officially allowed in failure route is because of how the newly 
added branches are processed, so you might have problems when the enum 
query returns more than one result. Otherwise is perfectly safe.
Just to give you an example of the branch issue: the enum_query() 
function stores the first URI (from result) in RURI and the rest of them 
as branches; so, if the query returns A, B and C (ordered by q), you 
will have A in RURI and B + C in branches. As failure route does not use 
RURI anymore, you need to do a append_branch() to move A also as a 
branch -> you have B,C,A order now which conflicts with q.

if you do not have multiple results, you can safely do from 
failure_route the enum_query() and append_branch().

regards,
bogdan
