[Freeswitch-users] Getting multicast paging to work

[Bote Man]

Per
https://freeswitch.org/confluence/display/FREESWITCH/mod_esf

"The packets sent are *always* converted to G.711 mu-Law / PCMU (8khz)
because some phones (Snom for example) won't accept other codecs via
multicast."

If the phones only accept G.729 and not G.711 then you are out of luck, I'm
afraid.

But also, when the pbx shows
  Destination port: 8000
but FS shows
  Destination port: irdmi

It makes me wonder what in the world is going on there. I mean, if it showed
the same in both of them, then OK; but what port number is associated with
irdmi? If it's not 8000, then you have found another important difference.
That must be 2 different installations of Wireshark since one shows real
time stamps and the other shows serial log time elapsed.

Turn off the port name lookup in Wireshark and just compare the raw port
numbers.
