I have an issue with IP phones in one of the remote site. Not all the phones, but some phones go power down and power up after exactly an hour. While comparing the configuration of working phones with phones which have issues, I can see 802.1x Authentication under Product Specific Configuration Layout is User Controlled for non working phones, and enabled for working phones. While going through CiscoSysLog, I get the reason code for EndPointUnregistered event is 13 which is a  KeepAliveTimeout.   I've changed the 802.1x setting and asked the user for monitoring the occurrence of the issue, i am yet to get a response from them.   Before I see an help on this topic, I am curious to know  if any one has experienced similar kind of issues before.   CUCM Version : 8.6.2 IP Phones : 796X       ...

Hi All, I would require all your help to make our my fax machine working. Kindly find my flow below. Analog phone --> FXS --> MGCP GW (IDDGW1) --> CUCM 9.1.2 --> SIP Trunk --> SIP GW (IDDGW1) --> E1 ISDN The gateway IDDGW1 communicates to CUCM using SIP protocol, but the FXS endpoints alone are registered as MGCP endpoints.   Now the problem is, every time I make outbound fax it fails with communication error result. I have done some troubleshooting from my end and the failure reason I could see from SIP side as 488 and 415 error messages. I have T.38 and Modem pass through enabled from CUCM MGCP GW page as well as in gateway side. The primary fax protocol is configured as T.38 and fall back as modem pass through. Since I felt the gateway is having some issues in processing T.38 media, I have configured it to do pass though but no luck. I see posts saying about fax protocol between IP networks, but in this case the gateway is connected to an ISDN provider. Could you tell me how the fax works in this setup and what is the recommended mechanism for this type of setup to work? I even tried adjusting baud rate to 14000 since I found codec is being used was G711, and also zeroed the NSF values. But no luck.   Could some one help me here with right direction?   Thank You, Lajith ... View more
