PBX Firmware: 5.211.65-15
PBX Service Pack: 22.214.171.124
Did a big upgrade over the weekend (Trixbox to Freepbx), approximately 280 phone system. Had trouble with the Grandstream GXP2110 phones - unable to program key functions - speedial, intercom, etc - simply won’t update the phone configuration. I didn’t have this issue with the other Grandstream models (GXP2000, GXP2141, GXP2100, etc).
Could you have a look when you get a chance?
Overall, the upgrade went well and the Commercial endpoint has been a plus for me. I’m happy with it.
