[SR-Users] record_route_advertised_address causes null send socket error

Hello,

if you control the freeswitches or change where they send
traffic/receive traffic, then I recommend to use two listen parameters
with advertise address, like:

listen=udp:my.ip.ad.dr:5060 advertise publicsrv:5060

listen=udp:my.ip.ad.dr:5080

and carriers will be linked to my.ip.ad.dr:5060, while for freeswitch
you use udp:my.ip.ad.dr:5080. You can use
force_send_socket()/set_send_socket() or $fs to enforce a specific
socket for sending traffic (e.g., towards freeswitch or carriers).

There will be two record-route headers, but, besides enforcing sockets,
everything else will be done automatically.

Cheers,
Daniel
