Hubertus R. Posted June 10, 2012 Report Share Posted June 10, 2012 Hello all, I'm running successfully a SnomONE v18.104.22.1685 on a Windows 2008R2. In the local network I have some Snom 360,370 and 870 connected and they all can successfully call outbound and internal as well as receive calls. Now I also got some clients in a second branch that is connected through OpenVPN to the main network. The manual provisioning of those Snom 370s was successful and I can call those phones and establish the call successfully. Only when trying to call from those devices somewhere else, it fails. Both when trying to call one of the extensions in the main network and when trying to call outbound (through berofix Gateway) from this branch, the calls won't establish. But when dropping the call then, the call is established. But as then initiating extension already aborted, the end of the line is dead. I can exclude routing problems for sure. Before SnomOne we used an Asterisk and due to the VPN and thereby reduced MTU., I had to enable the packet fragmentation. http://wiki.snom.com/FAQ/How_to_solve_problems_with_outgoing_calls_in_firmware_version_8%3F Afterwards this setup worked. But now with SnomOne both enabling this feature as well as short SIP headers, I can't make any outgoing call successfully. Anybody has an idea how to solve this issue? I can of course provide detailed log information, but please give me a hint what you need. I don't want to spam this forum with logs. Calling from a PC with XLite4 in this network successfully establishes a call. Also using one of the extensions for the Snom phones....
