[SIPForum-discussion] One way talk path

[dinesh gupta]

Hi Punita,



As every one say take a ethereal call trace (wireshark) it is right way to
track your problem. If you are using Firewall in your network it may be
blocking some RTP port. You should check you have allowed all media RTP port
in firewall.

You should also check

1-NAT

2- Codec negotiation in SDP


Thanks
