[Serusers] disconnect

Hi everyone, I have a little problem. My network looks like this: x-lite softphone on mac xlite-softphone on win grandstream budgetone 100 ip phone ser proxy (freebsd port build) VEGA gateway Incoming calls work great. But outgoing calls are being disconnected after 16 seconds. Now i talked to grandstream people and i have two versions of x-lite, the new version b1101 and the old one. With the old version the outgoing calls are going fine, but the new version is not working. They told me that the old version is working because it's not using the Branch ID. The new one does, so does the ip phone, hence it's not working. I did send him the trace files and everything. Now i guess my question is : is it ser's fault or vega's fault? Did anyone experience simmilar problem? I can send you the trace files if you need them. Srbo Cvetkovic | CityNet, Inc. srbo(a)city-net.com | Pittsburgh, PA voice: 412.481.5406 | fax: 412.431.1315
