Hi Asif, Sorry for late response. The link given by you was extremely useful. I got access point cum router. I created DHCP pool on Cisco router and after that i configured the access point with router. access point received ip from dhcp pool. i created one more dhcp pool on access point  to distribute ip on end devices such as pc, server etc. After that i linked more than 1 access point to the cisco router and divided the bandwidth as desired by access points. The link given above to distribute bandwidth  https://supportforums.cisco.com/discussion/10956426/limiting-bandwidth-cisco-router-possible-1800-series      was very useful for me.   Thank You once again Asif          ...

It is almost similar.  IP Phones (5001, 5002)  --------FXO and BRI port 2911 -----sip dial-peer to --------grand-----FXO port Grand----IP Phones (1001,1002) My question is that Can I make call from grand pbx phone (1001) to outside telephone number  using the FXO or BRI port of Cisco2911? For example, I make call using line 1001 to any outside telephone number but I want to establish connection using the trunk port in 2911 router not fxo grand. In Your flowchart mentioned above in your post, Can I make call from analog phone 2 to outside world telephone number using the port fxo 2911?   Regards ... View more

Thanks for having interest. Simply, there are two IP PBX routers. One router is Cisco2911 and another PBX is Non Cisco (Grandstreem). Both PBX are trunked (peered). Therefore, I can make calls on each others local extensions. What I need is to use the local trunk lines of one pbx from the extension of another PBX. Is it possible to do that?  If any confusion let me know. i will try my best to explain.  Thank You   Regards ... View more

Hi  Now it has completed peering each other. Pinging each others public ip was successful. The mistake was the following: sip   bind control source-interface GigabitEthernet0/1.15   bind media source-interface GigabitEthernet0/1.15 As soon as I negate above commands on Cisco 2911 as PBX it started peering with remote Grandsim PBX.   Can Anyone discuss how the bind interface command was stoping it to peer with another PBX?   Regards ...

Hi I found solution of it. Bind port was on fastethernet 0/1.15. It was supposed to be on  Dialer0 interface coz it has public ip address   Thank You Guys   Regards.   ... View more

Hi  In the above debug ccsip log, call is going to 1001@10.15.1.1. It should go to 1001@122.163.84.55 as 1001 extension is available on remote IP PBX (grandsim ).      Regards ... View more

Hi, I did it. Still same. I think packets are not out to public IP.
