I just finished my initial configuration of named components.
Base is UCM6202 with IP-Trunk (Germany)
Main Phone is a GXV3240.
Mobile Phones are two DP720 @ DP750.
I have outbound and inbound Routes, but calling out is working instantly for the GXV, while it lasts about 20 seconds if I call an external number with one of the mobile phones until the target rings.
The CDR of the call says 20 seconds if I hang up directly.
Any ideas where I can start? I think I compared all extension settings and SIP settings, but probably missed something
Edit: just tested it again with the GXV. Also a Delay. With only the GXV attached there was no delay. With 3 extensions there is.
