Hello community,   is there a way to change the phone model of an existing phone button template? I know there is the feature safe feature for newer phones However I am curious for the completeness sake. I couldn't find anything related to it in BAT. Thank you in advance. ... View more

Hello Cisco Community,   I am currently configuring trustpoints on a ISR router. The hierarchy looks like that: root --> subca --> router certificate. I will create 2 trustpoints where the 1st will reference the root-ca and the 2nd one the subca and router certificate.   I am aware of the fact, that the chain of trust needs to be established. I check several configurations and some mentioned the command chain-validation none (for the Root-CA); chain-validation "name of upper trustpoint e.g. subca".   The question is, whether the command chain-validation ... needs to configured in order to setup a clean configuration on the router.   Any feedback is appreciated. ...

Hello Cisco community,   As I was building the chain of trust on a router, I realized that there are two commands that seem to do the same. In order to add the intermediary certificate to a trustpoint I normally would use the command: crypto pki authenticate subca After that I would add the router certificate to that trustpoint with the following command: crypto pki import subca certificate    Here are my questions:   1:   Could I use the command crypto pki authenticate subca to import the router certificate or does the router do something different with the crypto pki import subca certificate?   2:   It seems like common practice to create a separate trustpoint for the root certificate and create another one for the subca and the router certificate. What's the idea behind that.   Any input is appreciated. Thank you. ... View more

Hi community,   I just configured a scrypt type 9 password and wanted to use it for my console login. It seems like the ISR 4331 cannot process this password. Is this a known limitation or might it be a bug.   Thank you in advance.   Best regards   Thomas ... View more

Hello world,   I tried to install a LSC on a Telepresence MX300 unit. I didn't work until I changed the "Authentication Mode" to "Null String". First it was set to "By existing Certificate (precedence to MIC)" which never worked. (Error: Invalid credentials...) My guess would be that the MIC installed on the unit cannot be validated by CUCM. Here is a excerpt of the certificate:   Certificate: Data: Version: 1 (0x0) Serial Number: d8:4b:7b:51:ac:64:c5:70 Signature Algorithm: sha1WithRSAEncryption Issuer: C=US, O=Cisco Systems, Inc. Validity Not Before: May 6 10:16:47 2014 GMT Not After : Apr 12 10:16:47 2114 GMT Subject: C=US, O=Cisco Systems, Inc. Subject Public Key Info: Public Key Algorithm: rsaEncryption Public-Key: (2048 bit)  We have the standard Cisco root CAs installed on our system:  - Cisco_Root_CA_2048 - Cisco_Root_CA_M2 - CAP_RTP_002   Any ideas as to why it fails with the MIC validation?   Thank you.  ...

Hello world,   I was wondering whether CUCM honors the codec preference list order if a call is setup between two phones in different regions. The scenario uses SIP Early Offer. After the called device presents CUCM with its capable codecs, does the CUCM honor the order of the codec preference list of the calling device or called device. If yes the phone call would use OPUS if not it would use G.722.   Both Phones understand the mentioned codecs. Region A uses a codec preference list that has e.g. OPUS listed first followed by G.722. Region B uses a codec preference list that has e.g. G.722 listed first and OPUS listed as second codec choice. Between Region A and B we have a maximum Audio bitrate of 64 kbps. Location bandwith is unlimited.   Thank you in advance. ... View more
