It turns out this was a mistake in the asterisk config and its relationship with osmo-cc. It was resolved when I corrected the mistake and works perfectly, sorry for the noise.

Hi Dave,

Can you try to add "-v 0" to command line? This way you get detailed message frame content in debug output. After the line "transaction.c: 245 info : Transaction state PAGE -> PAGE SEND" you will get several lines with all elements of the paging message. What do they look like for both cases (console and osmo-cc mode)? In my case they look both like this:

Hi All,

I have an issue where paging doesn't work when using osmo-cc-endpoint with tacs and a USRP1

I can place calls from the MS out over osmo-cc-endpoint via my pbx to the pstn with no problems, if I try to call back in via sip it always fails to page the MS

Running the -x option I can call between two MS stations with no issues, paging works and the calls connect

Here is an example if I run the command I can make calls from the mobile device and hear the music, I can also press d and call the MS back with no problem, paging appears to work 9/10 times

./tacs --sdr-uhd --channel 323 --channel 318 --channel 320 --samplerate 581818 --sdr-tx-antenna TX/RX --sdr-rx-antenna RX2 2342123456

Is this likely to the sdr, I can use multiple boards for tx/rx but I can't figure out how to expose the different cards in uhd as the list command doesn't seem to work for antenna

Any help appreciated.

Thanks

Dave
