Hi, If we propose Cisco Expressway on Cisco BE6k, how many applications we can have with medium density? AS i check dockwiki, 4 apps + 1 mandatory prime collaboration. So my understanding is on a medium density BE6K bundle, we can have 4 apps (CUCM + CUC + Expressway C + Expressway E) and 1 mandatory prime collab provisioning. Is my understanding about sizing is correct? Is there anything else for Mgmt or ELM is also required?? Ajay           ... View more

Hi,            One of our customer needs SIP trunking services. Cuurently they have 3 different Legacy TDM PBXs & is willing to use existing PBXs rather than moving to IP PBX. How can we acheive this? Option 1: TDM PBX ----> QSIG --->Cisco ISRG2 Gateway (H.323) ----> SIP -----> SIP Service provider network Option 2: TDM PBX ----> QSIG ---> H.323 On Cisco ISRG2 Gateway ----> SIP on CUBE (same ISRG2 running H.323 GW) ---> SIP Service provider network Which option is suitable??? As far as i know, Option 1 will suffice since there is no IP PBX and TDM doesn't understand IP so gateway will take care of everything and CUBE licenses are not needed. QSIG --> H.323 --->SIP signal conversion and transcoding can be taken care by gateways itself. Is my understanding correct and we can go with Option1 or not?? What other consideration needs to be taken or we should go with Option 2?? Secondly if i am choosing option 2 and running CUBE & Gateway both on same router, do i need to consider CPU utilization also. E.g. Cisco 2901 supports 100 SIP sesions and if i need TDM - IP conversion also for 80 sessions, will there be any effect on CPU utilization or i just need to put CUBE licenses and CPU utilization will not have a considerable impact. I was going through the Gateway section of SRND but i found the information a bit ambigutous to conclude for solution ... View more

Hi All, I wanted to know if there is any place on website where i can find all the devices which are or about to be EoS. It is difficult to find each and every product individually but perhaps last resort if no other option. This will help me in recommending the right product for custmer and i don't have to search the sea all the time. ... View more

Hi, One of my customer looking for migration from CUCM 7.1(5) to Version 8.x I am yet not sure which specific flavor of Version 8.x should i move to. There are 5 Subscriber and 1 Publisher along with CUPS, Unity Server, IPCC Express, ARC servers, ISR gateways ang VG2XX gateways. I need to find out which version of 8.x will be suitable and hardware and software impacts i need to figure out before migration. Thanks, Ajay ... View more

Hi, I have a customer with 2 different clusters in the network. Currently there is no intercluster link in between. Cluster A has 2 VGs with H.323 running on it. Can i add those same 2 VGs as part of Cluster B as well so that i can directly send the call from VGs of cluster A to Cluster B without routing Via publisher of Cluster A??? Reason behind doing this is that those 2 VGs (in clsuter A) are having TDM PBX behind them and i dont want to route those calls via the publisher. I am planning to have intercluster trunk as well which will carry only IPT calls in between the clsuters. I believe logically this is possible but never implemented before. Site is very criticial and could not find any doc to justify this, need some help here. If needed i can create a small diagram and attach here. Thanks in Anticipation, Ajay ... View more
