Can I mix long distance and local SIP trunks?

Yes. We often mix long distance SIP trunks with local SIP trunks. By least-cost routing long distance calls over the long distance trunks, you save the maximum amount of money.

Can I fax over SIP?

Yes, most SIP providers support G.711 or T.38 faxing protocols. We’ve been told that faxing over SIP trunks is about 95% reliable.

Do I need a SIP-enabled Phone System?

No. We have many customers that use an Integrated Access Device (IAD) that converts the SIP trunks back to traditional analog or PRI connections.
