So here is what I have done so far.
I was running Incredible PBX 13-12.2 on centos os 6.7
First I did a yum-update and rebooted.
That upgraded the OS to centos 6.10
I already have refresh tokens for 2 of my GV accounts.
so I ran the following script
cd /root
wget
http://incrediblepbx.com/gvsip-naf-gui.tar.gz
tar zxvf gvsip-naf-gui.tar.gz
rm -f gvsip-naf-gui.tar.gz
cd gvsip-naf
./install-gvsip
That upgraded incrediblepbx from 13-12.2 to 13-13.
However, the asterisk version is still 13.7 and not 13.22
I also added GVSIP 2 trunks by running ./install-gvsip one more time.
I appreared to have created both custom GVSIP trunks.
However, I does not registers with google voice..
Should I run the script upgrade-asterisk-to-current ?
