Hi! I try to register SIP phone. I configured UCM End user and other settings like was discribed in a cisco's guide about SIP-phones. But redistration failed. It is not a network communication problem. I find this error in UCM logs "Rejecting foreign host/domain" about my SIP-phone. How can I find out, what does it means? How can I debug SIP-registration on UCM? Is it possible to get standart SIP error codes from UCM?
Yes, UCM works fine with SIP. I find out that my problem is NAT. It's not a problem with SIP digest anymore.
I create static NAT on ASA to redirect SIP udp 5060 to UCM. It work fine, BUT: UCM reseve SIP packets with destination address of ASA5510's outside interface inside SIP packet and reject it. ASA doesn't do NAT inside SIP data, It does NAT only for IP packet.
