VoIP (SIP) though an Soho91

Oct 18, 2005 0 Replies

Hello !



I have actually a config-problem which starts to drive me crazy :



I simply try to use an VoIP client though my Soho91 . The config of the Client seems OK, it works when I use an different DLS router (a standard home-solution) without any special settings on it.



Now i try the same using my Cisco It seems that the INVITE-message is sent, authentication at the SIP-proxy works. I even get back an answer from the SIP-Proxy (something like 'your call is important to us ......') but then I get an timeout error.



I allready disabled everything regarding firewall (enabling this raises the trouble - even if all neccessary ports should be open).



As I said, using an 'cheapo' DLS-router everything works fine.



Any ideas where to search for the problem ?
