[OpenSIPS-Users] errors with Ekiga

[Barsan Liviu]

Hello,

We have OpenSIPs and MediaProxy working well with clients like Bria and Blink, 
but appears errors with Ekiga, for example at Presence (SUBSCRIBE, PUBLISH, 
NOTIFY).
Below is what we dump with ngrep, can be seen that the server send a Bad Event 
for SUBSCRIBE coming from Ekiga:

What do you think, is Ekiga partially incompatible with OpenSIPs or we miss 
something?
We notice that for Ekiga is not possible to set Presence details.

Thanks,
Liviu
