Single-Stage Dialing Through Any OBi Trunk Using SIP
Momo:
Ok, now I can connect and place the call... But I can't hear anything. Even the other party can't hear. Port 5060 and 5061 are forwarded to the OBI. Do I need to forward any other ports ?

Try forwarding RTP port range 16600 - 16998 (UDP protocol). Range covers both Obi100/110 RTP defaults in ITSP Profiles A & B.

Thanks infin8loop for your suggestion. I've tried this. The other party can hear me but I can't hear them. I've even tried to put OBI's IP in DMZ. Same result.

Try turning off any SIP, ALG, SPI or NAT restriction settings, or turning on gaming mode, if applicable. (from a Stewart post on another board). I've seen this suggestion more than once. My router doesn't have any of these settings so I don't know if they will help or not.
FWIW: I have the following set for my SIP (not GV) providers:
ITSP Profile X -> General -> STUNEnable : checked
ITSP Profile X -> General -> STUNServer : stun.ideasip.com
ITSP Profile X -> General -> STUNServerPort: 3478
ITSP Profile X -> General -> X_ICEEnable : checked
ITSP Profile X -> General -> X_SymmetricRTPEnable : checked
Where Profile X is A or B as applicable. Either or both of the last two options (X_) above can probably be set or maybe neither.
I have no idea if full-duplex versus half-duplex has anything to do with the RTP voice stream but I also have the OBi set to full duplex: http://www.obitalk.com/forum/index.php?topic=2438.msg15767#msg15767

Thanks infin8loop for your help. It's not working. If I place a call from "line", it's working. But If I place a call through SP1 or SP2, I can't hear the other party. I've changed everything. Ports forwarding, full duplex etc...
I also have 2 other questions :
1) I have 2 Obi's (One set in a remote place)
Obi1: local IP is 192.168.0.14 hostname obi1xxx.no-ip.biz
Obi2: local IP is 192.168.0.101 hostname obi2xxx.no-ip.biz
I need help to configure this part
User Settings -> User Defined DigitMaps -> User Defined Digit MapX
Label : p2p
DigitMap : (<n*:>(@@.)<:@192.168.1.140:sip_port>|<n*:>(@@.)<:@hostname:sip_port>)
Can you please tell me if it's correct ?
Obi1's Digitmap: (<1*:>(@@.)<:@192.168.0.14:5061>|<2*:>(@@.)<:@obi2xxx.no-ip.biz:5061>)
Obi2's Digitmap: (<1*:>(@@.)<:@192.168.0.101:5061>|<2*:>(@@.)<:@obi1xxx.no-ip.biz:5061>)
2) Can we use speed dials with this method ? I've tried it but it's not working. Do we need change anything to make it work.
Thanks again for your help guys.
