So, it now seems confirmed..
Grandstream GXP1782 FW 1.0.1.116 does not work with the NOTIFY process of Kamailio 5.4.4
Grandstream GXP1782 FW 1.0.1.119 DOES...
On review of the Grandstream 1.0.1.118 update, • Fixed BLFs are not updating sometimes
when using certain SIP servers
So, there ya go...

I just updated the firmware on the GXP1782 phones and when they booted up ------ The BLFs
came right up and are working...
Let's hope it's not just some cosmic annoying coincidence....
Time for much testing..

The careful eye will notice NOTHING CHANGED.....
Almost nothing... Of course the branch and (from/from/to) tags are different BUT THATS
IT...
So, not working, go for food, working... I changed nothing.
I thought it was the never change version attribute in the dialog-info but, maybe not.
Has anyone seen this ? If so, how did you get past it ?
In case you're new to this thread, these are Grandstream GXP1782 desk phones.
When I change the DNS A record for the host and point it to a FreeSWITCH system, the BLFs
are fine. It's just when they reach Kamailio 5.4.4 that they don't sync up
properly.
Any pointers are welcome...
Jerry
