Niall,

Most likely NAT issues with the RTP streams in SIP.

Blueface very helpfully provide IAX trunks when requested. IAX packets
bundle the messaging and RTP into the same packets avoiding NAT issues.

If I initiate a call between a hard phone and a soft phone tcpdump shows me UDB packets whizzing back and forth between the two, but I guess they're not speaking the same language, for whatever reason.
