Hello, I was able to install OpenSIPS and RTPProxy ( taken from here ) on Amazon EC2, and onn the mobile side I am using PJSIP library. I am able to make VOIP call from ios simulator <-> iphone5 and it works well, if the iphone5 is connected to a WiFi, but if I turn off the WiFi on the device and try to make the VOIP call using 3G, I can't hear any voice, although the connection and the call are established ( confirmed ).
Maybe you can give me some advice or suggestions. Where should I look for an error? On the server side or on the mobile side?? Here is the info about the call ( 3G, without the voice ), which was given by PJSIP: ====================================================================== Call time: 00h:05m:07s, 1st res in 6688 ms, conn in 6689ms #0 audio speex @16kHz, sendrecv, peer=- SRTP status: Not active Crypto-suite: RX pt=98, last update:00h:00m:00.641s ago total 0pkt 0B (0B +IP hdr) @avg=0bps/0bps pkt loss=0 (0.0%), discrd=0 (0.0%), dup=0 (0.0%), reord=0 (0.0%) (msec) min avg max last dev loss period: 0.000 0.000 0.000 0.000 0.000 jitter : 0.000 0.000 0.000 0.000 0.000 TX pt=98, ptime=20, last update:never total 12.8Kpkt 397.0KB (910.1KB +IP hdr) @avg=10.3Kbps/23.6Kbps pkt loss=0 (0.0%), dup=0 (0.0%), reorder=0 (0.0%) (msec) min avg max last dev loss period: 0.000 0.000 0.000 0.000 0.000 jitter : 0.000 0.000 0.000 0.000 0.000 RTT msec : 0.000 0.000 0.000 0.000 0.000 ====================================================================== OpenSIPS doesn't give any errors, it shows that: INFO:rtpproxy:rtpp_test: rtp proxy <udp:my_private_ip:9000> found, support for it enabled And here is my opensips.cfg file: ====================================================================== ####### Global Parameters ######### debug=3 log_stderror=no log_facility=LOG_LOCAL1 fork=yes children=4 advertised_address="my_public_ip" #debug=6 #fork=no #log_stderror=yes #disable_dns_blacklist=no auto_aliases=yes listen=udp:my_private_ip:5060 disable_tcp=no listen=tcp:my_private_ip:5060 alias=my_public_ip:5060 alias=mydomain.com:5060 disable_tls=yes ####### Modules Section ######## #set module path mpath="/usr/lib64/opensips/modules/" #### SIGNALING module loadmodule "signaling.so" #### StateLess module loadmodule "sl.so" #### Transaction Module loadmodule "tm.so" modparam("tm", "fr_timer", 5) modparam("tm", "fr_inv_timer", 30) modparam("tm", "restart_fr_on_each_reply", 0) modparam("tm", "onreply_avp_mode", 1) #### Record Route Module loadmodule "rr.so" /* do not append from tag to the RR (no need for this script) */ modparam("rr", "append_fromtag", 0) #### MAX ForWarD module loadmodule "maxfwd.so" #### SIP MSG OPerationS module loadmodule "sipmsgops.so" #### FIFO Management Interface loadmodule "mi_fifo.so" modparam("mi_fifo", "fifo_name", "/tmp/opensips_fifo") modparam("mi_fifo", "fifo_mode", 0666) #### URI module loadmodule "uri.so" modparam("uri", "use_uri_table", 0) #### USeR LOCation module loadmodule "usrloc.so" modparam("usrloc", "nat_bflag", "NAT") modparam("usrloc", "db_mode", 0) #### NAT modules loadmodule "nathelper.so" modparam("nathelper", "natping_interval", 10) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "received_avp", "$avp(received_nh)") loadmodule "rtpproxy.so" modparam("rtpproxy", "rtpproxy_sock", "udp:my_private_ip:9000") # CUSTOMIZE ME #### REGISTRAR module loadmodule "registrar.so" modparam("registrar", "tcp_persistent_flag", "TCP_PERSISTENT") #### ACCounting module loadmodule "acc.so" /* what special events should be accounted ? */ modparam("acc", "early_media", 0) modparam("acc", "report_cancels", 0) /* by default we do not adjust the direct of the sequential requests. if you enable this parameter, be sure the enable "append_fromtag" in "rr" module */ modparam("acc", "detect_direction", 0) modparam("acc", "failed_transaction_flag", "ACC_FAILED") /* account triggers (flags) */ modparam("acc", "log_flag", "ACC_DO") modparam("acc", "log_missed_flag", "ACC_MISSED") ====================================================================== Any help will be highly appreciated!
