Quote from: chuby007 on June 09, 2012, 05:10:20 PMbasically have my pots line as an FXO to make my POTS line accesible via SIP URI
it works... however I dial out.. no voice on any side !
If the calling device is on the same LAN as the OBi, I don't know why it's not working; use SIP Debug to see where RTP is going and where the OBi told the client to send it.
Otherwise, this is likely a NAT issue. Assuming worst case (both client and OBi are behind separate NATs), try the following:
For ITSP Profile B -> General, turn on STUNEnable, set STUNServer to a working STUN server such as
stun.counterpath.net and turn on X_SymmetricRTPEnable. Also, in your router, forward the UDP ports corresponding to the range specified by LocalPortMin to LocalPortMax to the private static (or statically assigned by DHCP) address of the OBi. If your router does not support port range forwarding, you can safely change LocalPortMax to 16806 and just forward UDP 16800, 16802, 16804 and 16806.
If it still doesn't work, try setting up STUN on the client and forwarding its RTP port range.
If no luck, post details about your setup (router makes/models, modem makes/models, client device or software).
