[Freeswitch-users] making outbound call with IPv6

[Jason White]

Turning on all of the Sofia debugging options reveals the following.

FS sends out the invite (UDP, 1245 bytes).

Then we get:

nta: timer shortened to 500 ms
tport_wakeup_pri(0x2490700): events ERR
tport_udp_error: icmp(6) message was truncated (at 832)

The IPv6 address that sent the "message too long" error is presumably that of
a router between my FreeSWITCH box and my friend's FreeSWITCH box.

Is there a way around this?
