<param name="sip-ip" value="1.2.3.4"/><param name=" rtp-ip" value="auto"/> The SIP option I set to my real external (elastic) IP and it broke the SIP comms - i removed that because SIP is working correctly.
The RTP option was set as auto but this doesn't appear to have made any noticeable difference.
I haven't found any detailed information about what those fields actually do so apologies for the shot-in-the-dark approach here.
Any further ideas?

Hello Luke - didn't expect you to pop up - hope all is going well for you! Merry Xmas Cool thanks guys, i'll have a read. I do have a general understanding of NAT but i'm not able to recognise whether an issue is due to my box configuration or something natty just from looking at a trace - maybe i'm hoping for too much! You know, if my wireshark trace is showing RTP being initialised to a remote internal IP i'm assuming that means its not correct... Maybe its a case of Jack of all trades! ______________________________ Callum Guy X-on Framlingham Technology Centre Station Road, Framlingham, Suffolk, IP13 9EZ T 0333 332 0116 E callum.guy@x-on.co.uk X-on is a trading name of Storacall Technology Ltd a limited company registered in England and Wales Registered Office : Avaland House, 110 London Road, Apsley, Hemel Hempstead, Herts, HP3 9SD Company Registration No. 2578478 This email has been sent from X-on.The contents and attachments are confidential to the sender and the intended addressees.If the message is received by anyone other than the addressee please return the message to the sender by replying to it and then delete the message from your computer without copying or disclosing the contents to anyone.Opinions, conclusions and statements of intent in this email are those of the sender and do not bind X-on unless confirmed by authorised representatives independently of this message.While best endeavours have been taken to avoid transmission of viruses, it is the responsibility of the recipient to scan for these.Please note emails sent to and from X-on are routinely monitored for record keeping and quality control, to ensure regulatory compliance and prevent unauthorised use of our systems.
