Advantec distributes and integrates IP phones on the AdvantecVoIP platform. Its services focus on business VoIP: calls travel as digital packets over the internet rather than analog signals

The system supports virtual extensions, automatic routing and shared lines

Advantec offers cordless and desktop phones. Cordless handsets allow you to dial and press Send or the speaker button to place a call and answer calls. Desk phones use a handset, speaker or headset. SpectrumVoIP also supports softphones and mobile apps for users who need additional mobility.

Connect the phone to a network port and power source. Phones obtain an IP address automatically; if a static IP is required, support can manually configure the IP address, subnet mask, gateway and DNS. Disable SIP ALG on your router and check your network quality via speed and ping tests

Cordless: dial the number and press Send or the speaker button; to answer, press Send, tap Accept or use the speaker. Desk phone: dial and lift the handset or press Speaker/Headset to dial; answer by lifting the handset or pressing the speaker.

On cordless phones, press Options and choose Hold or press New Call to automatically place the call on hold. On desk phones, press the Hold button; selecting another line key also holds the call. Retrieve the call by pressing the line key where it is parked.

Blind transfer: on cordless phones, press Transfer, dial the destination and hang up; on desk phones, press Transfer, dial and hang up.

Attended transfer: on either device, dial the destination, wait for them to answer, speak, then press Transfer again to complete.

Voicemail or intercom: dial 5001 + extension to send directly to voicemail or 08 + extension for an intercom call.

Call parking allows you to place a call on a shared “parking” extension. On cordless phones, press the asterisk three times (***); the call is parked on a slot such as 701, 702 or 703. Dial the parking slot to retrieve it. Desktop phones have Park buttons; unlike hold, parking frees the line so another person can pick up the call.

The default voicemail PIN is 1234. Press Message and dial 5001 on your phone to access messages. From outside the office, call your extension; when the greeting starts, press * and enter your password. You can also check voicemails via the web portal and set up email notifications with attachments so that messages are automatically removed from the phone inbox.

Dial *72 + number to forward all calls. To disable forwarding, dial *73. This works on both cordless and desk phones.

On a cordless phone, press Options → Conference → OK, dial the third participant and press Send; once they answer, press Conference again. On a desk phone, press Conference, dial the third party, and press Conference again after they answer.

To make an announcement, select Call Features → Paging on a cordless phone or press the Paging key on a desk phone. To start an intercom call with a specific user, dial 08 + extension.

The caller ID has two parts: number (the callback number) and name (CNAM). You can change the number per user or for the whole account through admin portals or by contacting support. The CNAM must be registered with a national database, is limited to 15 characters, and can only be updated via support. Dial 933 to check the device’s E‑911 number and address

Some cellular networks do not support CNAM transmission; in that case, only the number and sometimes the rate center (city) are shown. For example, a number with CNAM “SPECTRUMVOIP” may appear as “469‑429‑2500 ALLEN, TX” on T‑Mobile

Carriers label numbers as “Scam Likely” when they detect suspicious patterns. To reduce the risk, comply with telemarketing laws, avoid high-volume automated campaigns, ask customers to save your number, and change numbers if necessary. If your number is already flagged, contact your carrier, ask customers to mark it as safe, use other communication channels, and register your number with analytics providers.

Network quality depends on latency, packet loss and jitter. Run speed and ping tests to ensure adequate bandwidth and low delays. Run speed and ping tests to ensure adequate bandwidth and low delays. Use static IPs only if recommended by support.

Yes. If you are not using a AdvantecVoIP-provided router, a technician can manually assign a static IP to your phone. You must supply the desired IP address, subnet mask, gateway and DNS servers; this information is also required if you use your own router.

Each additional number costs US $2.95 per month. You’ll need to specify whether the number is local or toll-free and its purpose (voice, fax, SMS, user, department, auto attendant, call queue); provide the desired CNAM (up to 15 characters); and list preferred and alternate area codes and digits along with the city or rate center. Submit the request via your project manager or support (phone, chat or email).

You may return unused devices within 30 days in original condition and packaging. Returns of refurbished items are only accepted if defective, and items under contract are not returnable. Customers must pay return shipping; refunds are issued within about 5–7 business days after inspection. New devices come with a one-year manufacturer’s warranty; this warranty is separate from any lease and does not cover third-party phones. To claim warranty service, contact support with your extension number, device MAC address and a callback number; support may ship a replacement and provide return instructions.

Call recording is available but disabled by default; to enable it, contact support. Recordings are stored free for the first 30 days. Extended storage costs US $2.99 per extension for each additional 30‑day block (e.g. 60 days = $2.99/ext, 90 days = $5.98/ext). You cannot choose specific extensions for extended storage. During a call you can start and stop recording with *98 and *99 respectively.

Check that the phone has power, is connected to the correct network port and that your internet connection is active. If the issue persists, contact SpectrumVoIP support and provide your extension number, the phone’s MAC address and a callback number.
