Here is our network design.

                          internet -- ASA -- SIP Phones
The symptom is i can receive incoming calls but can't make outbound calls. Also, when I receive incoming calls, either parties can't hear anything. I remember that I deleted "inspect sip" under global-policy and put it back.
Somehow the SIP Phones stop working. I attached asa configuration, debug sip, and asa log.

I really need your help and thank you all in advance.

<Configuration>

global (outside) 1 interface
nat (outside) 1 10.100.10.0 255.255.255.0   --> SIP phones IP Address range: 10.100.10.208/28


object-group protocol DM_INLINE_PROTOCOL_1
 protocol-object udp
 protocol-object tcp

access-list outside_access_in_1 extended permit object-group DM_INLINE_PROTOCOL_1 any any eq sip

policy-map type inspect dns preset_dns_map
 parameters
  message-length maximum 512
policy-map global_policy
 class inspection_default
  inspect dns preset_dns_map
  inspect ftp
  inspect h323 h225

  inspect rsh
  inspect rtsp
  inspect esmtp
  inspect sqlnet
  inspect skinny
  inspect xdmcp
  inspect sip
  inspect netbios
  inspect tftp
  inspect icmp
!
service-policy global_policy global

<xlate result>               --> x.y.z.66 is the asa outside interface IP which SIP phones are translated to
asa# sh xlate | i 10.100.10.214

Where in you configuration are you allowing the RTP traffic which carries the SIP Audio?  Port 5060 is only used for call setup and teardown.

Is this a new installation, or a new problem on an existing installation? Also, what phones are you using?

Mere-mortal is on the ball; there seem to be no references to media or audio in the SIP debug log, and no RTP traffic = silence, even though the call is established.

I take it that the SIP debug log is from the phone itself?

Somehow the phones start working again....didn't do any....guess it was provider's issue...

Again, Thank you for your responses.
