Hello Sergiu,

We allow multiple contacts to register on single account. They can have different properties. On step 1 I'm looking for something specific which can be different for different contacts. If I understood correctly *setbflag* and *isbflagset* can set and check flags for different branches independently.

Thank you!

I might be wrong, but isn't ACK part of a transaction? If so, you'd need to use *setflag*/*isflagset*

Cheers.

Hello everyone!

I'm not sure if I correctly understood the description of functions *isbflagset* and *isbflagset* so once again I'm asking for help :)

Here is what I do:

1. Asterisk sends INVITE to Kamailio. Kamailio performs lookup of

available contacts and then few checks in branch_route. I'm adding *setbflag("17", $T_branch_idx);* there. 2. Later in route[NATMANAGE] I added *if (isbflagset("17", $T_branch_idx)) {* and additional logic. *isbflagset* results in *true* (for same INVITE). 3. Finally one of UACs responds with 200 OK. Asterisk generates ACK packet that gets in route[NATMANAGE]. *isbflagset* results in *false*.

So my question is: shouldn't *isbflagset* be *true* for ACK too since it's the same branch or I interpreted these fenctions incorrectly?

Branches are a creature of transactions. It follows that “branch flags” are transaction-persistent flags at the branch level, rather than scoped to the transaction as a whole.

ACKs constitute a separate transaction.

Then.. I don't know, lol

But the fact that ACKs belong or not to even different transactions (depending on whether positive or negative reply) must be playing a role here.

Good luck.

Hello again,

I've just noticed that if new branch is created after using *t_suspend* and *t_continue*, branch flag can not be used. Not sure if it can not be set or checked. Doues anyone know about potential problems with such configuration?

Thanks!

Hello Alex,

Thank you for the clarification. Now I understand this behavior.
