I have captured the SIP packets for my VTech VSP 735.
After the subscribe succeeds, I get a NOTIFY from FreeSwitch to the Phone that includes “ Messages-Waiting: no”.
Can anyone tell me why? Or better still tell me how to enable MWI for this terminal. I went to the docs the parameter suggested.
Below is a partial sip dump and the Directory entry for the phone. Any help would really be greatly appreciated.
