How long does it take to get a DID number?
Once you purchase a DID number it's activated immediately, though a handful of countries that require extra verification can take a little longer.
Can I choose my own DID number?
Yes — pick one from the online ordering flow and it's activated instantly after purchase.
What equipment do I need for SIP trunking?
A SIP trunk works with any SIP-based IP PBX — no extra hardware required beyond what your PBX already needs.
Do I get notified if a fax sent via email-to-fax goes through?
Yes — a delivery notification is sent back to the source email address.
Can I send a fax to multiple recipients at once?
Yes — add multiple addresses in the email "To" field and each one receives the fax.
Can I send faxes from my phone using email-to-fax?
Yes, without any trouble — it works the same as sending from a desktop email client.
How long are call detail records (CDRs) available?
Call detail records are stored and available in the portal for 90 days.
Does Cloud PBX support transferring calls off-site?
Yes — a user can transfer a live call to an external number, and automatic transfers to an external number can be configured too.
How is voice quality kept consistent across regions?
Trunk.us routes each call to the nearest regional data center in the Cal4Care Group network to keep latency and voice quality consistent.
Do I need extra hardware to send or receive a fax?
None at all — it works almost exactly like sending an email.
