Second line of SPA 1001

Hi list,

I've got a WRT router with siproxd running and a Linksys SPA 1001. The SPA 
features 2 ``lines'' what means that I can register with 2 SIP accounts. For 
the 2 ``lines'', the SPA uses different SIP ports (5062 and 9999). The two 
SIP accounts have different user ids.

If I configure only 1 line, everything works fine. But as soon as I configure 
a second line, dialing works, but sound doesn't. A tcpdump on the router 
shows, that there is incoming and outgoing traffic on the RTP ports and the 
SIP traffic looks reasonable to me too.

Does anybody have an idea what could be wrong?

Thanks
Peter
