So, I can talk with my grandstream to another grandstream with direct IP dialing. But, when I try to call a dlink phone (or the dlink calls me) it will ring through but there is no audio.
I have, most of the time, over 95% LQ and NLQ. I am also able to do video calls to other grandstreams.
Any suggestions?
TIA

This may not be applicable in this instance since one phone can ring another, but on multi-line phones, make sure that at least one account is set to port 5060 (standard sip prt). Multi-line (multi-account) phones have different ports associated with each line. This is how incoming calls know which button to show up on.
I've set the preferred codec on my grandstreams to G729A/B. Seems to work better with Linphone and Cisco phones.
