Hi everybody;
The issue is that I want to build IP telephony network in the office , the devices I have is the following:
- Internet connection with ISP and connect via router
- The router has POST port that connect to PSTN
- Many HP switches and Poe Switch and also Cisco Switch
- Many IP phones from different vendors (Cisco , AVAYA, Huawei, grandstream) and also Polycom SoundStation.
Side problem:
When I enter the router configuration page it shows me an VOIP ip address but it does not work when I ping it by my command prompt it will not respond
And the ISP say it does not enable the VOIP for us because it is different service need to paid for , if is that the case why the router is preconfigured to have their VOIP dress
The questions:
Q1) could I by this only component establish IP telephony system and if no what the necessary components to be added?
Q2) should I order SIP trunks from the ISP to establish the IP telephony system or it is not necessary and the system could work without it
Q3) could the IP phones from different vendors connect to each other?
Q4) is IP PBX necessary to be used for the system to work
Q5) could I use IP PBX to connect my IP phones to the PTSN network via POTS port in the router
Q6) could I use the cloud to handle my calls without ISP like VOIP server not related to the ISP and what service providers are the best in such solution specially in the middle east
The request:
1- Answer the earlier questions with most cost effective and best solutions
2- Write all main components for the IP telephony to able to make the following:
a- Dail internally and externally
b- Conference call
My add another project with the freelancer who answer to collaborate to build the system.
