Keeping a SIP softphone alive on a mobile device has historically been a hard problem \u2014 iOS and Android both kill background processes to save battery, which means the app loses its SIP registration and incoming calls are missed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Siperb solves this at the infrastructure level. When a call arrives for your extension, Siperb\u2019s proxy sends a push notification directly to your device via Apple APNs (iOS) or Google FCM (Android). The operating system wakes the app, it re-registers, and your phone rings \u2014 whether the app was in the background, the screen was locked, or the device had just restarted.<\/p>\n\n\n\n<p class=\"wp-block-hb-message is-style-info wp-block-hb-message--withicon wp-block-paragraph\">Push notifications are included on the free Personal plan. See the full technical detail in <a href=\"\/kb\/mobile-push-notifications\/\">Siperb Mobile \u2014 Push Notifications for Any PBX \u2192<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Works with any SIP PBX<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Siperb\u2019s proxy sits between your mobile device and your PBX, handling the translation and the push integration. Your PBX sees a standard SIP registration \u2014 there is nothing to configure on the PBX side beyond allowing external registration. If you can provision a SIP extension, Siperb can deliver it to a mobile device with push notifications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This includes Asterisk and FreePBX, which between them power the majority of self-hosted PBX deployments worldwide. See <a href=\"\/kb\/asterisk-softphone\/\">Asterisk Softphone \u2192<\/a> for a step-by-step Asterisk setup guide.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">iOS and Android<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Both platforms are fully supported with platform-native push implementations:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><span class=\"wp-rich-text-font-awesome-icon wp-font-awesome-icon\"><svg aria-hidden=\"true\" focusable=\"false\" data-prefix=\"fab\" data-icon=\"apple\" class=\"svg-inline--fa fa-apple \" role=\"img\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 384 512\"><path fill=\"currentColor\" d=\"M319.1 268.7c-.2-36.7 16.4-64.4 50-84.8-18.8-26.9-47.2-41.7-84.7-44.6-35.5-2.8-74.3 20.7-88.5 20.7-15 0-49.4-19.7-76.4-19.7-55.8 .9-115.1 44.5-115.1 133.2 0 26.2 4.8 53.3 14.4 81.2 12.8 36.7 59 126.7 107.2 125.2 25.2-.6 43-17.9 75.8-17.9 31.8 0 48.3 17.9 76.4 17.9 48.6-.7 90.4-82.5 102.6-119.3-65.2-30.7-61.7-90-61.7-91.9zM262.5 104.5c27.3-32.4 24.8-61.9 24-72.5-24.1 1.4-52 16.4-67.9 34.9-17.5 19.8-27.8 44.3-25.6 71.9 26.1 2 49.9-11.4 69.5-34.3z\"><\/path><\/svg><\/span><strong>iOS<\/strong> (18+) \u2014 uses Apple PushKit (VoIP push), giving calls the same OS priority as the native Phone app. Rings reliably through locked screens, Do Not Disturb exceptions, and battery saver mode.<\/li>\n\n\n\n<li><span class=\"wp-rich-text-font-awesome-icon wp-font-awesome-icon\"><svg aria-hidden=\"true\" focusable=\"false\" data-prefix=\"fab\" data-icon=\"android\" class=\"svg-inline--fa fa-android \" role=\"img\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\"><path fill=\"currentColor\" d=\"M420.5 253.9a24 24 0 1 1 0 48 24 24 0 1 1 0-48zm-265.1 0a24 24 0 1 1 0 48 24 24 0 1 1 0-48zm273.7-96.5l47.9-83c.8-1.1 1.3-2.4 1.5-3.8s.2-2.7-.1-4.1-.9-2.6-1.7-3.7-1.8-2-3-2.7-2.5-1.1-3.9-1.3-2.7 0-4 .4-2.5 1.1-3.6 1.9-1.9 2-2.5 3.2l-48.5 84.1c-38.8-17.4-80.8-26.4-123.3-26.4s-84.5 9-123.3 26.4L116.2 64.4c-.6-1.2-1.5-2.3-2.5-3.2s-2.3-1.5-3.6-1.9-2.7-.5-4-.4-2.7 .6-3.9 1.3-2.2 1.6-3 2.7-1.4 2.4-1.7 3.7-.3 2.7-.1 4.1 .8 2.6 1.5 3.8l47.9 83C64.5 202.2 8.2 285.5 0 384l576 0c-8.2-98.5-64.5-181.8-146.9-226.6z\"><\/path><\/svg><\/span><strong>Android<\/strong> (Android 8 \/ SDK26) \u2014 uses Firebase Cloud Messaging (FCM) with a high-priority flag, delivering consistent wake-up behaviour across manufacturers and Android versions.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Full softphone features on mobile<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Push notifications get the call to your device.
