<div>Sorry, actually the documentation confused me.</div>
<div><br>
</div>
<div>You are correct in the way that it should work if the do_routing() and route_to_gw() are really pushing the functions on the end of the AVP. However, they must not be doing that because that is not the operation. To modify your example:</div>
<div><br>
</div>
<div>
<div># first time avp_gw_id is set</div>
<div>is_from_gw(, i); # function adds gw1 to AVP</div>
<div><br>
</div>
<div>If I access the AVP without an index I get gw1.</div>
<div><br>
</div>
<div>route_to_gw("gw2,gw3,gw4");</div>
<div># function adds gw2, gw3, gw4 to AVP</div>
</div>
<div><br>
</div>
<div>If I access the AVP without an index I still get gw1. Accessing AVP[1] gives gw2.</div>

<div>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.</div>

<div>I am currently using the same workaround of clearing out the AVPs prior to each DROUTING module call that populates them.</div>

<div dir="ltr">Hello Aron,
<div>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).

<div dir="ltr">Hello Opensips list,
<div><br>
</div>
<div>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.</div>
<div>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().</div>
<div>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?</div>
