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 registra=
tion
time. To further look into this, a detailed debug log of siproxd is neede=
d.

Best regards,
/Thomas
