The IP address will be voiced to the user. • The default username and password should both be **admin**. ![](https://support.mightycall.com/hs-fs/hubfs/Knowledge%20Base%20Import/downloads.intercomcdn.comio510258935574cb722ee408e55b50aa717index.png?width=600&height=216&name=downloads.intercomcdn.comio510258935574cb722ee408e55b50aa717index.png) **NOTE**: if entering the adapter's IP address does not provide you with a web GUI, the adapter most likely has its web interface disabled, and must be logged into via the LAN port on the back of the adapter to have remote administration enabled. ### Registration Once logged into the SPA112, select the **Quick setup** tab in the top left corner. ![](https://support.mightycall.com/hs-fs/hubfs/Knowledge%20Base%20Import/downloads.intercomcdn.comio51025916742f5d844563ead179a6a90c3index.png?width=600&height=279&name=downloads.intercomcdn.comio51025916742f5d844563ead179a6a90c3index.png)   Fill in the **Proxy**, **User ID**, **Password **fields.​ You can specify anything in **Display name**, as it will only appear on calls that terminate to other MightyCall customers. Get your credentials here: **Settings > Forwarding Numbers > Get connection details**. Click **Submit** in the lower-left corner of the SPA112 admin UI when done. Once the equipment is done saving the configuration, select the **Voice** tab at the top of the interface. **Line 1** should now show as **Registered**. ![](https://support.mightycall.com/hs-fs/hubfs/Knowledge%20Base%20Import/downloads.intercomcdn.comio51025937468471eccfeb62244d55daeccindex.png?width=600&height=73&name=downloads.intercomcdn.comio51025937468471eccfeb62244d55daeccindex.png) **Dial plan** 3-digit extension dial plan: `(*xxx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.)` 4-digit extension dial plan: `(*xxxx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.)` ### Voice Tab Navigate to **Voice > Line 1**.

Several have been tested and have been documented below. ![](https://support.mightycall.com/hs-fs/hubfs/Knowledge%20Base%20Import/downloads.intercomcdn.comio510260397105ba2cd0a1044a16a43d5b3index.png?width=600&height=538&name=downloads.intercomcdn.comio510260397105ba2cd0a1044a16a43d5b3index.png) ### Bonus: Call transfer Call transfer can be a challenge when it comes to analogue phones. Since it is not as obvious as with the SIP phones, here is a small guide on how to transfer a call if using an analog phone with an adapter: 1. Have a call already established 2. Press the flash key on the phone 3. User should now hear a dial tone 4. Dial the number you wish to transfer to 5. Once the call connects, the user may announce the transfer to the destination party 6. Pressing flash again will join the two calls, allowing all three parties to speak as if conferenced 7. The user may now hang up to complete the transfer. - [MightyCall Call Center](https://support.mightycall.com/mightycall-call-center?hsLang=en#main-content) - [Profile & Settings](https://support.mightycall.com/mightycall-call-center?hsLang=en#profile-settings) - [Subscription & Billing](https://support.mightycall.com/mightycall-call-center?hsLang=en#subscription-billing) - [Payment Methods](https://support.mightycall.com/mightycall-call-center?hsLang=en#payment-methods) - [Auto Dialer](https://support.mightycall.com/mightycall-call-center?hsLang=en#auto-dialer) - [Calling & Messaging](https://support.mightycall.com/mightycall-call-center?hsLang=en#calling-messaging) - [Messaging Compliance](https://support.mightycall.com/mightycall-call-center?hsLang=en#messaging-compliance) - [Call Flow Setup](https://support.mightycall.com/mightycall-call-center?hsLang=en#call-flow-setup) - [Numbers](https://support.mightycall.com/mightycall-call-center?hsLang=en#numbers) - [Team Management](https://support.mightycall.com/mightycall-call-center?hsLang=en#team-management) - [Workspaces](https://support.mightycall.com/mightycall-call-center?hsLang=en#workspaces) - [Reports](https://support.mightycall.com/mightycall-call-center?hsLang=en#reports) - [Mobile App](https://support.mightycall.com/mightycall-call-center?hsLang=en#mobile-app) - [Desktop App](https://support.mightycall.com/mightycall-call-center?hsLang=en#desktop-app) - [Integrations](https://support.mightycall.com/mightycall-call-center?hsLang=en#integrations) - [Deskphone Guides](https://support.mightycall.com/mightycall-call-center?hsLang=en#deskphone-guides) - [FAQs](https://support.mightycall.com/mightycall-call-center?hsLang=en#faqs) - [MightyCall Classic](https://support.mightycall.com/mightycall-classic?hsLang=en#main-content) - [Personal Settings](https://support.mightycall.com/mightycall-classic?hsLang=en#personal-settings) - [Subscription & Billing](https://support.mightycall.com/mightycall-classic?hsLang=en#subscription-billing) - [Calling & Messaging](https://support.mightycall.com/mightycall-classic?hsLang=en#calling-messaging) - [Messaging Compliance](https://support.mightycall.com/mightycall-classic?hsLang=en#messaging-compliance) - [Call Flow](https://support.mightycall.com/mightycall-classic?hsLang=en#call-flow) - [Team & Roles](https://support.mightycall.com/mightycall-classic?hsLang=en#team-roles) - [Business Numbers](https://support.mightycall.com/mightycall-classic?hsLang=en#business-numbers) - [Mobile App](https://support.mightycall.com/mightycall-classic?hsLang=en#mobile-app) - [Integrations](https://support.mightycall.com/mightycall-classic?hsLang=en#integrations) - [Deskphone Guides](https://support.mightycall.com/mightycall-classic?hsLang=en#deskphone-guides) - [FAQs](https://support.mightycall.com/mightycall-classic?hsLang=en#faqs) [mailto:support@mightycall.com](mailto:support@mightycall.com) Copyright © 2025, MightyCall
