  • Adjusting the IP phone

    IP-telephony and VoIP
    As an ATS, the Grandstream UCM 6202 was used.
    The external numbers:
    I used 3 SIP numbers from Kyivstar (for local calls), one number of them 5 channel, the rest one channel;
    Virorista 3 SIP numbers from Lifsel, one number 5 channel remains one channel
    Use GSM gateway GOIP-4 for 3 rooms on 7 cards
    For 40 analog phones I used the gateway Grandstream GXW4248.
    It was possible to install the IP phone using the Grandstream GXP1610 and for the mobile employees of the Gigaset C530A IP with additional pipes.
    I installed an IVR with the rows.
