[SR-Users] Foward REGISTER to all dispatcher members

[Kees Meijs - SIGNET B.V.]

Dear list members,

Currently I'm using the dispatcher module to distribute traffic towards
media servers (being Asterisk, in my case). I'd like to forward REGISTER
requests to all (active) dispatcher members, e.g. using a short and
simple while loop.

Could someone please give me some pointers towards the right direction?
Is it for example possible to use the MI di_list functionality for
iterating over all the members?

Thanks in advance!

Best regards,
Kees

you can call ds_select_dst() for register request. The first selected
gateway is in dst_uri ($du), so that can be simply relayed.

Then you can access the rest of the destination via $avp(name) you sent
to dst_avp parameter:

-

In a while loop, you can append branches to register before relaying:

while($avp(name)!=$null) {
... # appends branch, etc..
$avp(name) = $null);
}
Iirc, also first selected destination is in this avp list, so you may
need to skip first entry.

Cheers,
Daniel
