| Advantages    | <ul><li>You can call directly from a browser with the Bitrix tab open. </li><li>You can call through the Bitrix24 mobile application. </li><li>The call comes to the user, depending on whether he started a working day or not. </li><li>Setting the logic of calls through the setting of telephony B24.</li></ul>                                                                                                                                                              | <ul><li>Call routing and voice traffic completely remain on the side of your PBX - reduces connection time and improves communication quality. </li><li>You do not need to reconfigure Asterisk, the connected IP-phones and soft-phones at workplaces will continue to work. </li><li>Telephony works with the closed Bitrix portal, calls and leads are created. </li><li>If Bitrix24 does not work, then telephony will continue to work, and after reconnecting, all calls will be downloaded to CRM. </li><li>Unlimited trunks and up to 100 simultaneous conversations (tested load)</li></ul> |
| Disadvantages | <ul><li>Voice traffic passes through Voximplant cloud telephony (servers are located in the Netherlands, which affects the speed of connection and quality of communication). </li><li>If B24 does not work, then telephony does not work.</li><li>Maximum 10 trunks and only 15 simultaneous conversations (lines) The logic of the call is configured only in B24. </li><li>Existing telephone sets and soft-phones need to be reconnected to Bitrix cloud telephony.</li></ul> | <ul><li>It is impossible to make a call from a browser, but you can use a soft background - an additional program on a computer or a smart background connected to Asterisk.</li></ul>                                                                                                                                                                                                                                                                                                                                                                                                               |
