    After upgrade form v14 to v15 I'm not able to receive any fax using T38 protocol on Nexvortex sip trunk. Wireshark does not telling me anything. There is a tona , strat negotiation and after 20 sec just drop connection. Does anyone have fax working on v15?

    First, make sure you use the latest SP. If already so, can you upload the trace, please?

    @vectra,

    Any luck with this? Also, are you just using the fax server or are you using an ATA?
