Configuration of adjacency on SBC

[bahar.rezazadeh19821]

Dear all

i am going to connect an ASR1000 to a softswitch as SBC in unified mode, but i get confused about the IP addresses of Peer, Local, remote which is used in below configuration:

adjacency sip To-Phone

signaling-address ipv4 ipv4_IP_address

signaling-port port_num

remote-address ipv4 ipv4_IP_address/prefix

signaling-peer peer_address

signaling-peer-port port_num. 

adjacency sip To-Softswitch

signaling-address ipv4 ipv4_IP_address

signaling-port port_num

remote-address ipv4 ipv4_IP_address/prefix

signaling-peer peer_address

signaling-peer-port port_num.

to configure the adjacency of Phone, what is the IP addresses of Peer? is it the IP address of IP-Phone or soft-phone?

to configure the adjacency of soft-switch, what is the IP address of "remote-address"?

there is a sample topology in attahced

thanks

Hi Bahar,

IP address of the peer would be the ip address of the endpoint who will use the adjancy.

Also "remote address" for soft switch would be range/subnet of Ip address who are allowed to use the adjacencies and Resi tri ticing any other apart from this.

Read this ,I believe you can get more info.

Hi Deepak

Thanks a lot for your response. 

As you said the adjacency of down link to the endpoint, is the IP address of endpoint(soft-phone-IP phone) so if there are 10000 phone in my network,  should I define 10000 adjacency one by one?!!!

am i right? 

I'v prepared a sample config, which is in attachment,would you please check it and let me know is it correct or not?

HI Bahar,

Peer address for an Adjacency would be the ip address for outgoing point.This is the point of contact for outgoing calls.So please ignore the previous answer.Also you need to activate DBE (Media) and SBE(Signalling) mode for it to work as unified mode. 

User attached sample config.thanks

Hi Deepak

Thanks for your quick response.

I have another question about the Signalling-address and media-address which we configure on SBE and DBE, what are those? Are they the physical IP address of the ASR interface?

In your sample config, the IP addresses of  signalling-address for each adjacency and also media address is unique(88.88.141.2 , 88.88.141.3 , 88.88.141.11).

so does it mean that there are 3 physical interface from ASR to connect to the network?

Is it possible to have just one link to the network?

Thanks
