Welcome to Unified Networking

Things get much simpler and easy when you want to configure SX20 as a Standalone device. This is a much needed feature when someone wants to use SX20 for Video conferencing but they don't have any telepresence equipment. Using H323 protocol we can configure SX20 as standalone device, where as SIP can be used in case of CUCM deployed environments. To configure SX20 as a standalone device, follow the below steps: 1. Enable H323 from network service 2. Select default call control protocol as H323 3. Select Mode to Off (Optional) 4. Go to H323 configuration page; System -- Configuration -- H323  5. Select Call setup mode: Direct 6. Port Allocation: Static 7. Under H323 Alias, Configure ID as Your SX20 Unit IP address.     Do not assign any URI under ID, leave it with just the IP address. URI will be configured only for       SIP, whereas H323 will work based on IP address only.    (Private or Public IP is immaterial, just assign whatever th...

Cisco collaboration meeting rooms is a cloud based conferencing technology offered by Cisco. CMR is basically a combination of Cisco's Webex and Spark. Webex is basically for initiating conferences through web, presentation sharing and online audio&Video calling. Whereas, Spark is a messaging client just like jabber. Through CMR, One can initiate an online web conference through any browser, any Cisco room based end points, android phones, desktop clients can join to the cmr conference. In order for an end point to join in the conference, any Room based end point must be registered to spark cloud. To register with spark cloud a unique 16 digit pin generated by cisco's partner is mandatory. Below is the video which shows how to add any room based end point to the spark cloud. Once the device is registered on spark cloud, it is good to join in the CMR.

Integrating cisco CUCM with Telepresence conductor What is Ad-hoc conferencing?                 Creating conference by pressing conference button, merge, join on the end point is called as ad-hoc conferencing. Rendezvous conferencing?                 A rendezvous conferencing is when dialing a conference bridge number directly by all the endpoints instead one adding other to conference. In ad-hoc conferencing: They use both xml rpc messaging. The destination for these sip and xml rpc messaging (to conductor) is configured by configuring a bridge number in the unified cm. This bridge number is then assigned to media resource group, and then media resource group is assigned to media resource group list and then finally this MRGL is assigned to a Device. In Rendezvous conferencing: For rendezvous conferencin...

Cisco CME DSP Issue If you are running through any of the following error, then this post is for you.  Applicable to Fxo, Fxs ports and PRI E1/T1 ports deployments. 1. Only one way communication is happening 2. Frequently getting the console message:  FLEXDSPRM-3-TDM_CONNECT: failed to connect voice-port (1/1/0) to dsp_channel(1/1/3) 3. Able to call but no audio The reason here, we can call it as a cisco bug or misbehaviour of the router. When there are frequent changes at one side of the PRI trunk or fxs port then router's dsp fails to function properly. Signalling works without any issues though. When this happens you might face one way audio through router. That means if you are having a pri trunk then calls in one direction, pbx --> router or router --> pbx works but not works in the reverse path. Even though if you are calls are working in both the ways, if you see this error, you might experience calls disconnecting in feature. So you should be awa...

Hello all,            In this, document i will tell you how to successfully integrate Cisco Call manager Express (CME) with any third party PBX with examples. This process is called PRI Trunking or PRI integration.           Recently i was into PRI integration with 3 Cisco routers (Cisco 3945, 2951 and 4130) with IRIS lite PBX.           Integrating a PBX is not a that hard as we think, but it's bit sensitive. Sensitive in the sense while during the PRI integration we just need to be careful while assigning the parameters, they should match at both ends, i.e., on PBX side and CME side as well.           The very first thing to consider for PRI trunking is   "cable".   Yes, the cable which needs to connected between PBX and CME should be a cross over cable. For connecting a cross over cable, at cisco side we should connect to 1,2 4,5. In PBX side we...

Bandwidth restricting/limiting/shaping with Sub-Interfaces in Cisco IOS The following port describes on what is bandwidth limiting and how we can configure them with Cisco routers which are configured with Sub-Interfaces. Scenario: Switch0 configure with 3 vlans Router0 configured with 3 sub-interfaces with correct vlan tags. switch <--> router configured as trunk port. Configuration in router:  Creating access lists that matches the LAN networks. access-list 101 permit ip any 192.168.10.0 0.0.0.255 access-list 102 permit ip any 192.168.20.0 0.0.0.255 access-list 103 permit ip any 192.168.30.0 0.0.0.255   Creating class-maps that maps to the LAN networks:   class-map match-all vlan10  match access-group 101 class-map match-all vlan20  match access-group 102 class-map match-all vlan30  match access-group 103 Note: here vlan10, vlan20, vlan30 are the names of the class-maps that we have cre...

Configuration of LACP & PAGP: LACP & PAGP: Link Aggregation Control Protocol and Port Aggregation Protocol both sounds same but the gap between these protocols is LACP is Open standard and can be used on any supported Product, where as PAGP is Cisco's proprietary and can be configured only in the Cisco devices. What are these these protocols? Generally we use trunk links to enable communication between two switches (for inter-vlan routing) when we use a single port for the trunk link (e.g., Gig port ) it gives us throughput of 1 Gbps, Making few more ports as trunk causes a loop and STP will block it from farming Configuring the LACP or PAGP gives us the capability to add multiple trunk links to a switch, without causing loops. So that providing more throughput. Port-Channel: When we have bundled multiple interfaces into a trunk group, A new logical interface is created automatically and its called as Port-Channel. When we configure this port channel inter...

CONVERTING CISCO CAP TO SAP / SAP TO CAP (lwap - Ap / Ap - Lwap): You can watch the video too...!!! Conversion of the AP's using downgrade or upgrade takes a lot of time and most of the times the IOS loaded will lead to an error, So Instead of that process i am going to use ROMMON recovery, It's a simple procedure for IOS changing. It will help a Network engineer's work a lot easier. ROMMON recovery is a process of Deleting the existing flash, and re-inserting our desired IOS. Follow the below  procedure. Mandatory Pre requirements: A PC with TFTP server installed. (Turn off Antivirus, Firewall in PC) Cisco AP which is to be converted. Console cable  Procedure: 1) Login to the CLI go to "privilege mode" . (Enable mode) 2) Execute the below command:      show flash: Output for the above command will be like this In the above output following are the firmware images: ap3g2-k9w8-tar.153-3.JBB5.tar ap3g2-k9w8-mx.152-2.JB2  We need to de...
