[Freeswitch-users] media problem afet 302

[Miha]

Hi Michael,

thank you very much for your help.

I manage to figure it out.

First I did <action application="export"
data="nolocal:sip_renegotiate_codec_on_reinvite=true" />

and this did not work. Then I did:

<action application="bridge"
data="{sip_renegotiate_codec_on_reinvite=true}sofia/export/......"
/>

and this happens to work. After 302 is made, PBX sends to
FS new sdp invite on g711a and fs change codec. I do not
get error codec any more.

As I read on wiki this nolocal or if I put variable in to
the bridge {} is should be the same but I guess in this
case is not the same.

Thanks Mihael again!!!

BR,
Miha
