[Freeswitch-users] Control of IPv6 vs. IPv4

[George F. Phelps]

Brian West,

 

With my mostly default, current configuration, I am seeing Freeswitch send out simultaneous IPv4 and IPv6 registration attempts — not just one or the other.

 

I am only configuring the (IPv4) IP address of the SIP proxy.  I assume Freeswitch is defaulting to use port 5060.  And empirically, it’s completely random as to which type of registration (IPv4 vs. IPv6) succeeds.  And if, for example, IPv6 registration succeeds, then the registration attempts for IPv4 continue retrying in the background.  See my “sofia status” output below —  IPv6=REGED and IPv4=TRYING (retry: 20s).

 

My specific question is what Freeswitch configuration should I change to only have one type of registration?  How do I: “…you should pick where you want your gateway to register at, and only allow it there and there only…”?

 

Thanks,

 

George

FreeSWITCH does one or the other, you should pick where you want your gateway to register at, and only allow it there and there only.

My VoIP provider supports both IPv4 and IPV6 registrations.  I can only have one registration active at a time.  Freeswitch is attempting both IPv4 and IPv6 connections.  Randomly, sometimes a IPv4 connection is the first (only) registration established; other times it is the IPv6 connection.

 

How to I configure Freeswitch to deterministically only attempt one type (my choice of either IPv4 or IPv6) of connection?
