Re: OpenBSC + * + LCR -> Problems with LCR (--with-gsm-bs)

Ellen Apolinar wrote: if you like to use lcr with gsm (bs or ms), then you cannot use asterisk channel driver. it only works with isdn. but you can use sip. in order to do that you may: - disable mISDN (--without-misdn) - enable sip (--with-sip), you also need to have sipsofia installed - add a sip interface (see default/interface.conf). then everything is possible without mISDN, but you cannot use isdn phones/lines in this setup. example to just connect GSM and SIP interface without routing: [GSM] gsm-bs tones yes earlyb no #rtp-bridge bridge SIP [SIP] sip <local ip>[:local sip port] <asterisk sip ip>[:asterisk sip port] tones no earlyb yes #rtp-bridge bridge GSM if asterisk and lcr run on the same machine, you need to change the sip port on asterisk or lcr side. if you like to use GSM codec on asterisk side, you may enable rtp-bridge. then the asterisk directly negotiates the codec with the phone. in this case GSM codec must be supported by asterisk. tested codecs are FR(standard) and EFR. regards, andreas
