thanks brian, yes, i am aware that sip is only responsible for signalling and therefor my conclusion was, that it has got something to do with nat / firewall / the router... meanwhile i´ve got it solved... although the sip-provider tried to convince me, that the misconfiguration is on my asterisks´ side, i penetrated the support until they looked over it again.... and... what should i say... finally they had to admit, that the router had a wrong acesslist. they corrected it and now it works.
