[Freeswitch-users] IPv6 endpoints on LAN getting Error Cause: 19 [NO_ANSWER]

[Rajil Saraswat]

Hello,

I have two Linphone clients connected to a PBX server on my LAN. Both
the sip clients are registered to the internal-ipv6 profile.
Unfortunately, i am not able to call between them. I get an error

 [INFO] mod_dptools.c:3436 Originate Failed.  Cause: NO_ANSWER

Any hints on why this may be happening?

Thanks
