Great to know that !! So the NAT configuration on Digium possibly corrupted or fragmented the sip packets for ACK. We can see this if you can collect the packet captures I mentioned in my earlier post this will conclusively prove if there were fragmented / dropped packets when the ACK was sent to the Cisco side or the Cisco gateway didn't even receive it . Hope this helps! Regards, Karthik Sivaram

Hello Carlos, The packet cap from the Digium does show ACKs being sent . Would you be able to collect 2 simultaneous packet captures one from the Digium and the other from the cisco gateway at the same time ? This will show us if the packets are fragmented or if the ack is not processed / received by the gateway also it will give us information on the timestamps for the exchanges on both ends . Here is the procedure to collect the packet capture from the cisco gateway :- http://www.cisco.com/c/en/us/support/docs/voice/h323/116078-technologies-technote-commandreference-00.html#anc5 Regards, Karthik Sivaram

Yes 9971 and 9951 are also sip phones hence they do not show up. The cme sip is a basic sip registrar hence any sip phone ( including third phones) can register with it as long as it meets the SIP RFC . There is no "show" command to tell you about the sip phone models however you can check the document I have specified in my previous post to tell you about the phone models supported in the srst version 10.
