Hi All. I am testing a GXP with an AWS hosted 3CX instance running 15.5.0 on Debian. I have an HTek UC926 and Snom 821 RPS provisioned and registered. I am now trying to get a Grandstream GXP2130 provisioned the same way but having some trouble. I followed the instructions here:
https://www.3cx.com/sip-phones/grandstream-gxp21-series/
I manually updated the firmware of the GS to 1.0.9.68.
The phone does not provision, I do not get the two reboots and login prompt on the phone itself, as described in the 3CX howto.
I've run Wireshark on pcaps from the phone itself, my router and PBX, all I am seeing are ACKs both ways. Well, I am seeing PSH, ACKs from the PBX side so I am guessing it's waiting on something more from the phone side. I don't have the benefit of seeing what AWS may or may not be blocking. Being that I have two other registered phones of different brands using the same method, I don't suspect the AWS firewall, unless Grandstream is sending something out of the ordinary. Any advice welcome and thanks in advance.
