Hi expert,

I have  strange issue with VOIP calls between two sites, the issue is when I dial from site B to site A the call is going fine,  but when I call from site A to site B also is going fine except with  Cisco IP Phone 7945 once they answer the call immediately goes down but If I try to reach another phone type all  calls going fine ……any suggestion why 7945 drops calls, here is  my setup details:

Site A info:

-          Call Processing : CUCM 7.0

-          Cisco IP Phones 7941 , 7911 & 7970

-          Cisco IP Phones is registered as SIP with CUCM 7.0

-          I add UC 500 “Site B” call processing as H.323 device

-          Configure route pattern , route list and route Group “UC 500”

Site B info:

-          Call Processing : UC 500

-          Cisco IP Phones 7945 , 7985 & Soft phone

-          Cisco IP Phones is registered as SCCP with UC500

-          Dial-peer already configured pointing to CUCM 7.0 “Site A” call processing


Please note that I attached the debug on UC 500  while I make calls:

Called Number: 406 (7945)

Calling number : 106  (7941)


Thanks in advance.

The main problem is that the systems were never meant to be networked.


Q. Can the Cisco Unified Communications 500 Series be networked with   Cisco Unified CME or Cisco Unified Communications Manager?
A. The   Cisco Unified Communications 500 Series can be networked with an   integrated services router-based Cisco Unified CME, but the Cisco   Unified Communications 500 Series does not work with Cisco Unified   Communications Manager.

The problem trying this is what you mention, it only works one way.
