I'm good too my friend. It is always good to hear from you. Sorry for delay, I was on vacation... You've mentioned having single interface wouldn't need a bind. Anyway, I setup with no bind and about the interfaces not sure how I would be able to use two interfaces as I have zero trust architecture in place and sharing internet circuit for both internet and voice/PSTN services. Anyway, everything is working fine even with no bind and having FW/NAT/DMZ to ITSP :-) Do you have that document saying Cisco recommends having two interface for security purposes? ... View more

Hey Deji, it has been a long time...I hope everything is fine with you! Let me put a new scenario. I'm deploying a new site which I have a CUBE/DMZ area with only one interface behind a Firewall which will be NAT traffic from Internet/ITSP to the only interface/private IP we have in the CUBE. And the CUBE/DMZ using same interface will be talking to the corp network CUCM. So, no bind will be needed. However, do you see any problem on that? As always nice post. Thank you, Gustavo! ...

I have that settings already. This feature is more to prevent toll fraud, and sip vicious is a kind of attack snooping the network.  I was wondering if using SIP Profile would prevent or block this option message with sip vicious. Thanks! ... View more

Hi Jay, I have a question. I'm trying to use this tool below: https://supportforums.cisco.com/document/12957466/tool-assist-packet-capture-and-analysis I did a packet capture from CUBE/4331 XE router, however not sure how to find out the hex dump from Wireshark in order to decode and paste to this tool from pcap file, if possible.  Thank you, Gustavo ...

Hello, What happens if I move the PVDM4-128 from motherboard to T1/E1 NIM module? Would I still be able to use for transcoder, etc? I just want to make sure as long as I'm going to use T1/E1 I must add a new PVDM on NIM module. Thank you! ... View more

Hey Yan, have you figured it out? Having the same issue... Thanks! ... View more

Did you get it fixed? I'm having the same situation, but in H323 GW. Thank you! ... View more

Great document. I was wondering if there is a work around for H323 as well. I tried all possible ways to send the original callerID via CFW to the PSTN with no success. It always shows either main number or callerID from my office, but never from the external originator callerID. I tried to add another rule 2 for voice translation in order to pass as it comes, but again the same results: voice translation-rule 1 rule 1 /^7412/ /412208/ (valid DID) rule 2 // // (pass as it is for redirect CFW calls back to PSTN) ps: I checked and my provider allows me to send whatever callerID back to the PSTN. I also tried those translate callback-number/redirect under voice translation-profile, but no success.  Please let me know if someone knows if is possible to show the originator calledID when the call is being forward back to the PSTN via H323. Thank you! Gustavo ... View more

Have you ever figured this out? I'm having a similar issue but mine is related to Voice traffic EF showing Packets marked 0. The ACL, class-map, policy-map, nested service policy applied into sub-interface with no IP all looks good, but still showing marked 0. I also have under this sub-interface bridge-group - BVI, not sure if that makes any difference... I also have another site working fine, but the only difference is the service policy is applied in the physical interface and there is an IP assigned to it. Any help is much appreciated! Thanks! ...
