hi
i have large voip udp packets over internet problems and i need the
transfer medium to be tcp. below is what i had in mind.
SIPp_client A (TCP out) -> (listen TCP) SER 1 (UDP out) --> Soft-switch
(UDP in /out only) --> (to) ring Client B (listen UDP)
Client A and Client B registers to above Soft-switch. All the above are
individual servers (Linux CentOS based)
i need help in a (conversion) ser.cfg. Can anyone post a sample ?? below
is my ser.cfg (tried using t_relay_to_udp(), rewritehost(),
rewritehostport(), forward functions BUT none seems to work the way i
want it to)
SER 1 == 192.168.10.203
Softswitch == 192.168.10.251
Client A == 192.168.10.221 or .236 (SIPp client-registered to
soft-switch successfully)
Client B == 192.168.x.x (registered to soft-switch successfully)
Thanks
