Re: OpenBSC with LCR/SIP

Hi Andreas, this is this mean a BTS behind NAT and a OpenBSC +LCR/freeswitch + sip phone on freeswitch will be able to communicate with good RTP ?

Would the IP.Access nanoBTS works behind a NAT with OpenBSC ?

i.e. two BTSs in two different locations behind NAT connecting to NITB. im trying to make a call, but it seems rtp has some problem.

hi kelum,

the NAT firewall should track the RTP frames from BTS behind NAT, so that frames from BSC outside NAT can find their way to the BTS. i suggest to sniff (tcpdump/wireshark) behind and before NAT, in order to localize the problem.
