Thanks for a great forum, I’ve found lots of very helpful posts here over the years. I’m hoping someone can help me figure out an issue I’m having with some of my Grandstream phones.
I’m having an issue provisioning both GXP2124 and GXP2170 phones with the Endpoint Manager (commercial). I have reproduced the same issue on multiple phones of each model. Phones work perfectly with the endpoint manager using any of the 1.0.7.xxx firmwares, but upgrading to 1.0.8.xxx or beyond (including the latest 220.127.116.11) results in a phone that is registered, but has no dial tone and can’t dial.
Phones show as registered to an account on the display and show up as registered in fop2. Making a call to the phone will trigger a missed call notification on the phone and send the call to busy voicemail. There is no dial tone and dial buttons are un-responsive.
If I clear the Endpoint manager generated configs from tftp, and do a factory reset, I can manually configure the phones and they connect to with no problems. This includes using call park and blf buttons. Everything works with manual config.
I tried exporting the config files from a GXP2170 and comparing them. I pasted to excel, sorted, put back into text files and ran a diff. There were lots of things different between the default config and the provisioned config. I’m not really sure where to look and was hoping someone has seen this or something similar and has a solution. One that I noticed was the dial patterns. Could that be the issue?
I’m a new user so it won’t let me upload the config files. Let me know if there’s a way I can add them.
I’m running a fresh and fully updated install with:
Endpoint Manager 18.104.22.168
Default Grandstream Base File
