gsm sim gsm.sim.conn at gmail.comHello, we are trying to setup a splitted gsm 2g network, all services are on different vm's, e.g. one machine for bsc ,one for bts ...! At all we have 6 different vm's on a local subnet 192.168.192.X: osmo-bts-trx (IP = .12) with osmo-trx to support N210 (192.168.10.6) with TRX IP 127.0.0.1 osmo-bsc - IP = .41 osmo-msc - IP = .42 osmo-hlr IP= .43 osmo-stp IP = .44 and also osmo-mgw (IP=.45) with 2 instances, one for osmo-bsc and the other for osmo-msc. If I'm try to call from mobile a to mobile b, I able to see that the call is incoming but a connection won't establish, the other mobile is ringing, if I pick up the call on mobile b, mobile a is still trying to connect. On osmo-bts-trx I get some errors: <000e> l1sap.c:96 RTP clock out of sync with lower layer: 320 vs 160 (1937437->1937446) <000e> l1sap.c:96 RTP clock out of sync with lower layer: 0 vs 160 (1937446->1937446) On osmo-mgw at bsc-side the output looks like: <0011> mgcp_protocol.c:453 CRCX: creating new connection ... <0011> mgcp_protocol.c:79 endpoint:15 RTP-setup: Endpoint is in loopback mode, stopping here! <0000> mgcp_network.c:188 endpoint:0x15 Failed to send dummy RTP packet. <0011> mgcp_protocol.c:653 CRCX: endpoint:0x15 connection successfully created <0011> mgcp_protocol.c:676 MDCX: modifying existing connection ... <0011> mgcp_sdp.c:333 Got media info via SDP: port 26360, payload 255 (unknown), duration 20, addr 192.168.192.12 <0011> mgcp_protocol.c:805 MDCX: endpoint:0x15 connection successfully modified <0011> mgcp_protocol.c:453 CRCX: creating new connection ... <0011> mgcp_sdp.c:333 Got media info via SDP: port 4002, payload 255 (unknown), duration 20, addr 192.168.192.45 <0011> mgcp_protocol.c:653 CRCX: endpoint:0x15 connection successfully created <0011> mgcp_protocol.c:453 CRCX: creating new connection ... <0011> mgcp_protocol.c:79 endpoint:16 RTP-setup: Endpoint is in loopback mode, stopping here! <0000> mgcp_network.c:188 endpoint:0x16 Failed to send dummy RTP packet. <0011> mgcp_protocol.c:653 CRCX: endpoint:0x16 connection successfully created <0011> mgcp_protocol.c:676 MDCX: modifying existing connection ... <0011> mgcp_sdp.c:333 Got media info via SDP: port 64810, payload 255 (unknown), duration 20, addr 192.168.192.12 <0011> mgcp_protocol.c:805 MDCX: endpoint:0x16 connection successfully modified <0011> mgcp_protocol.c:453 CRCX: creating new connection ... <0011> mgcp_sdp.c:333 Got media info via SDP: port 4004, payload 255 (unknown), duration 20, addr 192.168.192.45 <0011> mgcp_protocol.c:653 CRCX: endpoint:0x16 connection successfully created However, the osmo-mgw msc side reports following: <0011> mgcp_protocol.c:453 CRCX: creating new connection ... <0011> mgcp_protocol.c:79 endpoint:1 RTP-setup: Endpoint is in loopback mode, stopping here! <0000> mgcp_network.c:188 endpoint:0x1 Failed to send dummy RTP packet. <0011> mgcp_protocol.c:653 CRCX: endpoint:0x1 connection successfully created <0011> mgcp_protocol.c:453 CRCX: creating new connection ... <0011> mgcp_protocol.c:79 endpoint:2 RTP-setup: Endpoint is in loopback mode, stopping here! <0000> mgcp_network.c:188 endpoint:0x2 Failed to send dummy RTP packet. <0011> mgcp_protocol.c:653 CRCX: endpoint:0x2 connection successfully created Best Regards Sebastian -------------- next part -------------- An HTML attachment was scrubbed...
