Hey there ! I am excited that this topic started ;-) I am 40 yo guy from Poznan, Poland,
about 2 decades ago I had pleasure to work with NMT Centertel Dealer. It brings for me
great memories. Recently I managed to collect some NMT phones - at the moment I have more
than 10 fully functional NMT phones: Nokia 250, 350, 440, 450, 540, 550, 650, Benefon
Delta, Benefon Sigma, Benefon Spica, Motorola Associate 2000. I have four Baofeng
radios, buils Linux based pc, bought 2 USB cards and managed to compile, run and work
Osmocom - Analog and called phone to phone. Also Computer to phone over headphones. I
was also trying to launch LCR, bought ISDN card Fritz, and was attempting to use FritzBox
with built - in VOIP - Isdn gate and try to make my NMT phone call PSTN over Voip and
mISDN/LCR router. So far no succes. I am not a specialist - self learned electronic -
hobbyst. If I could afford it I would buy LimeSDR but for the moment it is a bit expensive
for me. Anyway - I have tried OSMO-CC-ENDPOINT as I realised that I will not need any
LCR / mISDN / asterisk anymore. I did try many times but all I can get is an update
about authentication error with my SIP provider. here is log : osmocom-analog connects
to osmo-cc-sip-endpoint, but it looks like SIP-Endpoint does not connects to my SIP
provider. I did forward 5060 ports to my linux pc, what could I do wrong: sip.c:1430 debug
: Event 29 from SIP stack received (handle=0x55cb861d7980) sip.c: 921 info : Received
REGISTER response: 401 Unauthorized (registration) sip.c: 943 debug : Register challenge

myPublicIP -v 0 Any ideas what do I do wrong? Many greetings for All people in
osmocom-analog subjects. I am fascinated about this historical technology. Would be very
happy if I could call somebody from my NMT phone ! Regards for all people who work with
osmocom-analog subject. Respect to all! Jacek
