I found similar behavior in my implementation, except that I use dr_routing()
instead of route_to_gw(). When the AVP is already populated, these functions
simply push on the end. This may be an implementation decision, but it is
certainly not intuitive or what I expected.
I am currently using the same workaround of clearing out the AVPs prior to each
DROUTING module call that populates them.

Subject: Re: [OpenSIPS-Users] Route_to_gw not pushing gw_id to the first index
of avp
Hello Aron,
After calling is_from_gw("-1","i") I don't need to use the index, because it is
the only value hold by the avp, but later in my script, if I call route_to_gw()
and use $avp(dr_gw_id), it still has the value previously pushed by
is_from_gw(). Then to get the gw id pushed by route_to_gw() I have either to
use the avp index (e.g. $avp(dr_gw_id)[1]) or I set $avp(dr_gw_id) to null
before calling route_to_gw() (which is what I am doing now).

I guess pushing to the last index of the avp is what's expected.
But how did you retrieve the gw_id from is_from_gw, did you use an explicit
index?

Hello Opensips list,
When using the route_to_gw() function, I noticed that the gw_id that is pushed
back to the avp wasn't matching the address actually selected by the drouting
engine.
After some investigation I noticed that earlier in my script I was calling the
is_from_gw() function with the 'i' flag which also pushes the gw_id to the avp
and this was the value I was seeing in my avp after calling the route_to_gw().
By debuging with the avp_print() function I could see that the route_to_gw()
does not pushes the gw_id to first index of the avp, but to the end of it. Any
reason for that or is it a bug?
Regards,
Patrick
