Setting up freeswitch server on Google cloud compute

Question

I am trying setup freeswitch server on google cloud compute (ubuntu 14.04) although it work fine for me locally, I seem to get the following error when I start freeswitch server on google cloud compute.Can any one explain?

2015-06-11 05:40:32.001508 [ERR] sofia.c:2853 Error Creating SIP UA for profile: internal-ipv6 (sip:mod_sofia@[::1]

The likely causes for this are:
1) Another application is already listening on the specified address.
2) The IP the profile is attempting to bind to is not local to this system.

I found answer for this myself at http://lists.freeswitch.org/mailman/listinfo/freeswitch-users

So this issue is related to ipv6. Since google didn't provide ipv6, I had to disable ipv6 in freeswitch

In conf/sip_profiles directory you will find files regarding ipv6,

    abcd@instance-1:/usr/local/freeswitch/conf/sip_profiles$ ls
    external  external-ipv6  external-ipv6.xml  external.xml  internal-ipv6.xml  internal.xml

In order to disable ipv6 in freeswitch we need to rename to something like external-ipv6.xml.inactive or we can move/remove these files.

But make sure you only rename/remove files/folders regarding ipv6, So here I removed files external-ipv6 , internal-ipv6.xml, external-ipv6.xml

And then restart Freeswitch server

EDIT:

BEFORE:

# ls
external  external-ipv6  external-ipv6.xml.inactive  external.xml  internal-ipv6.xml  internal.xml

AFTER:

# ls
external  external-ipv6.inactive  external-ipv6.xml.inactive  external.xml  internal-ipv6.xml.inactive  internal.xml
