I just Updated to10.13.66-22 and have lost the ability to have a more that one line active on a phone.
I would be able to place a call on hold and open a second line to make a outbound call. Also, when I am active on the phone, call just get a busy when the ext is called.
What setting should I be checking.
So I think I have a little more info now.
I and using the EPM and have the grandstream firmware 1.13 loaded in slot 1 and 1.17 loaded in slot 2
The firmware that is showing on my GXP2170 that is using slot 1 is 22.214.171.124
The firmware that is showing on my GXP2170 that is using slot 2 is 126.96.36.199
phones that are running the older firmware are able the hit any softkey and dial another call with others on hold.
the newer firmware is not allowing me to place a call on hold and dial another line, conference call or any feature that has more than 1 active call on the phone.
I’m kinda stuck where to look in the basefile if the issue is even there.
any thing would be helpful.
