Hi, I am new to Asterisk and am runing asterisk 1.2.9.1 on an OpenBSD box. With a few manuals I was able to set up some SIP providers with which outgoing and incoming calls work. However, there is one provider with which inbound calls don't work at all. The only apparent error/warning message is this WARNING[13688]: chan_sip.c:3527 process_sdp: Unable to lookup host in c= line, 'IN IP4 213.185.164.123213.185.164.123' Maybe someone knows how to fix this. Many thanks in advance. Here is my sip.conf with the troubling provider ---sip.conf--- [general] disallow=all allow=ulaw allow=alaw allow=ulaw allow=g729 allow=gsm allow=slinear ;qualify=no context=default bindport=5060 bindaddr=0.0.0.0 srvlookup=yes localnet=192.168.0.0/255.255.255.0 ; -------------------------------------------------------------------- ; ; Connection Data for SIP providers ; ; MobileCall register => 43720755555:XXXXX@sip001.mitacs.com/43720755555 ; --- ; SIP out [43720755555] type=peer username=43720755555 fromuser=43720755555 secret=XXXXX host=sip001.mitacs.com fromdomain=sip001.mitacs.com insecure=very nat=yes qualify=yes ; --- ; SIP in [Mitacs_in] type=peer fromdomain=sip001.mitacs.com host=sip001.mitacs.com nat=yes context=ankommend ; -------------------------------------------------------------------- ; ; Connection Data for SIP clients ; [39] callerid=Phone 3 <39> host=dynamic domain=192.168.0.82 user=39 secret=100 type=friend mailbox=39 nat=yes canreinvite=no qualify=yes ---EOF--- Here is my extensions.conf. ---extensions.conf--- [general] static=yes writeprotect=no [lokal] ; local extensions 30-29 exten => _3X,1,NoCDR() exten => _3X,n,Dial,SIP/${EXTEN}|55|Ttr ; SIP Provider [Mitacs_out] exten => _X.,1,SetCallerId,SIPID exten => _X.,2,Dial(SIP/${EXTEN}@43720755555,45,trg) exten => _X.,3,Hangup [default] include => lokal include => Mitacs_out [ankommend] exten => 43720755555,1,Dial,SIP/39|39|r ---EOF--- Finally, I enabled the debug log for the provider in question. It appears to me that incoming calls reach the Asterisk, but then something happens and the call doesn't get forwarded to my SIP-phone (I tried both soft-phones and hardware phones). As I said at the beginning, the only apparent error is the WARNING[27979] chan_sip.c: Unable to lookup host in c= line, 'IN IP4 213.185.164.123213.185.164.123'.
