ip nat inside source list 101 interface FastEthernet0/0/0 overload

ip nat inside source list 103 interface FastEthernet0/0/0 overload

ip nat inside source static udp 192.168.1.154 5060 66.128.121.27 5060 extendable

!

access-list 1 remark CCP_ACL Category=2

access-list 1 permit 192.168.1.0 0.0.0.255

access-list 2 remark RDP To Domain Server

access-list 101 permit tcp any any eq 4004

access-list 102 permit ip any any

access-list 102 deny   tcp any any eq 22

access-list 103 remark CCP_ACL Category=18

access-list 103 permit udp any any range 10000 20000

access-list 103 permit tcp any any eq 5222 established

access-list 103 permit udp any any eq 5060

access-list 110 permit udp any any range 10000 20000

Ok  I am at a loss  Probably something dumb  but i cant get sip signaling back on port 5060   Audio is good tho.  Any idea would be urgently welcome as the voice pbx is down.

First the access list used seems to be wrong, establisehd is not used in NAT ACL.

Second, by disabling SIP-ALG, things are unlikely to work

Then, can you explain in other words what is the problem that  you are xpereincing?

Finally, if you need guaranteed, time bound support get a smartnet contract, as this is a free forum.

5222 establied is for a data stream  that goes between an IM system with teh PBX

Not Getting Sip Signalling back from the carrier.

That is very possible since you disabled sip-alg, you're sending out private IP address and so thye are not responding.
