Sara_Donald Posted June 27, 2008 Report Share Posted June 27, 2008 I have this issue where the SNOM 370 works well with PBXNSIP but if I try to use the SNOM without the PBX I can register Ok with the SIP Provider but cannot make any calls, incoming calls are Ok. At first I thought it was a NAT issue but I tried the SNOM with DMZ set on the router and no firewall but still no outgoing calls, it just gets silence and doesnt even reach the SIP Server. I have tied this with several providers and all with the same result. Funny thought I had was maybe the SMOM is not being routed properly as I use a VPN on the router and I tried the SNOM without the VPN and low and behold calls could be made. My VPN has no restrictions on VoIP calls and allows any ports for this. So is there any thoughts on this as it is driving me mad to think it works with the pbx but not on its own? Sara Donald.
