Morning,Guys
Hope you are doing great.
I would like a little help here with something.
There is a customer (COMPANY “A”) which is using Cisco Call Manager Express 8.6.
On the same building, there is another internal company (COMPANY “B”)with is using a Linux based PBX system.
My question is, is it possible to integrate these two companies in terms of telephony services?
I mean…
Company “A” got its dial patterns…company “B” either.
Is it possible to add another dial-peer to this problem?
dial-peer voice 2 pots
description ConnectionToOtherCompany
destination-pattern 883.. (Example)
port 0/1/0 ß Which will be the port? I must connect another cable to the Router, my question is if this is on the Ethernet Interfaces?
forward-digits 9
The same will be done on the other PBX system…
But my question now is regarding to the CME router, cause this is where I will step in.
NOTE:
This is only for internal calls on BOTH companies.

Hi.
It's possibile through a SIP trunk between those two systems and configuring appropriate call routing and codec negotiation.
A possible dialpeer could be
dial-peer voice 10 voip
destination-pattern 883T
session-protocol sipv2
session-target ipv4:x.x.x.x:5060 (x.x.x.x is the ip address of the other PBX)
dtmf-relay rtp-nte
codec g711ulaw
no vad
If the other PBX requires sip authentication, you can define it under sip-ua configuration section on the CME
Before you start the integration, I suggest you to upgrade your system to the latest available IOS version
Please refer to the following link to have an idea.

Does the Linux based support SIP/h.323, if yes then check if the PBX is reachable from router by pinging it.
Then you use the Ethernet cable to connect from your router to the PBX.
Create a VoIP dial-peer pointing to the PBX with the destination ip-address for eg:
On the router
Dial-peer voice 1 VoIP
Destination-pattern 8.... >>>>>{num-plan of PBX}
Session target Ipv4: 0.0.0.0 >>>>{ip-add of PBX}
Dtmf-relay h245-alpha
Codec G711ulaw
No bad
It gig 0/0
H-323 VoIP interface
H-322 VoIP bind source add
Note: Do disable toll fraud and IP connectivity :
