[Serusers] setup

[Srbislav Cvetkovic]

Hello guys,

does anyone have a VEGA gateway, SER and Grandstream phones setup that 
works?  I am having some problems with outgoing calls. My call is being 
dropped after 16 seconds, while the incoming call is working properly. 
I have the latest firmware on my phones and here is my cnf file.

198.144.xxx.xxx - ser server
198.144.YYY.YYY - VEGA gateway
198.144.ZZZ.ZZZ - voicemail ( ser & sems )
