Re: [Siproxd-users] Configuration help needed for Cisco 7905

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hello Jeremy,

now you probabla need to capture a full debug log, including the REGISTER
sequence of teh Cisco phone and inlcude in an incoming call.

I still suspect that the Cisco phone is doing something funny at registration
time. To further look into this, a detailed debug log of siproxd is needed.

Best regards,
/Thomas
