Hay friends, I want to know how many simultaneous call can i do throughout a voip gateway from the internet call to the normal telephony network, because i want to see what implementation do i have to do multiple call from internet to differents telephones.

  • Please reply with a few more details of what you are planning on doing.

    For example:

    “I want my computer to originate 100 simultaneous calls to PSTN
    subscribers who have ‘opted-in’ to receive a 60 second political announcement.’

    If all you want to do is route calls, OpenSIPS may be a better tool.

  • I want to create a voip service, I do not know much about it, but the first thing I want to know if more than one client can make a call at the same time through internet to the PSTN, and what gateway should I use for this.

  • I think the first recommendation any of us will have is to research all you can as there are a lot of mistakes to be made in the telephony world and some of them can be expensive and/or dangerous. The kinds of questions you are asking are not bad to ask, but they do place you squarely at a beginner level.

    It is hard to answer your questions without having further information. What are you trying to accomplish with this system? Do you need to carry more than one call? What types of phone service are available where this will be installed?

    For example, a single POTS line will allow you one call in or out of the PSTN. This is not a limitation of Asterisk, this is a limitation on how POTS lines work. A PRI style connection (E1 or T1 depending on location)
    will allow many more (over 20 calls at once). A SIP trunk is only limited by the number of lines your trunking provider allows and the bandwidth of your internet connection. The gateway you would want to use will depend entirely on what type of connection to the PSTN you are using. A lot of manufacturers make hardware compatible with Asterisk for physical connections to the PSTN and a SIP trunk just requires an internet connection of sufficiently high bandwidth, low latency and a reasonably stable path to the SIP provider.

    Without knowing more about what you are aiming to do, it is hard for anyone to give you any specific help. You were earlier asked for a specific example of what you wish to accomplish. Please provide that and you will get more people responding.
