I am new here. I have a private setup with one grp2614 and a wp820 both working as they should. Both connected via two sip-numbers by our Germany internet provider.
Now I wanted to realize the possibility to call internally via direct IP call. But I cannot get it wo work.
Both devices are within the same subnet, having fixed IPs xxx.xxx.xxx.3 and xxx.xxx.xxx.2.
If I dial the IP of the WP820, no connection can be established. I do not find the possibility for starting an ip call from WP820’s side.
Does it whatsoever support direct ip call? In admin guide I found a hint in section phone settings (page 52) "this parametet must be set to “no” for direct ip calling to work. (random rtp port setting)
Really would appreciate your support in this. Thanks a lot, Michael
