For VoIP number formats calls in local, national and mobile cases we use 10 digit dialing (xx xxxx xxxx), with international calls prefixed with 001+ [CountryCode].

  • Domestic: 13106341794
  • International: 0016492885145

The following SIP capture provides an example of an outgoing call. Note that we validate your FROM as the full 11 digits.

  • A Party: 13106341794
  • B Party: 13104065498

CLI and Registration

If your PBX supports SIP Peering, we would generally recommend this method of connection over Registration.

The requirement is to present the originating CLI to the PSTN.

If you are connecting your PBX via Registration there are a number of options for ensuring the originating CLI is presented to the PSTN:

  • Individually Register each DID: Requires system admins to individually register each DID on the PBX.NB – On our platform, you can use your master account password to register each DID.
  • Restrict lines: In Lines Administrator, you can restrict individual lines to use their own UserName (and passwords). As with the “Individual Registration” option above you will need to individually register each line with us.
  • Outbound Trunking: Individual registration is convenient for situations where you are connecting a small office with say ten phones for example. The approach quickly becomes unworkable for offices with hundred of DIDs or handsets, not just for implementation but for ongoing management. If your switch doesn’t support SIP Peering, the preferred solution for Registration is Outbound Trunking, where you register a single DID as your trunk number, with all other numbers connecting out onto the PSTN via this single trunk number. To preserve the originating DID as the CLI your trunk number will present to us in the SIP URI sip:13106341700@tls.2talk.com while the outgoing CLI is presented in the FROM “13106341794″ contact

CLI and SIP Peering

By comparison to Registration, Peering is straight forward as you are connecting with us via a public WAN IP. In a Peering mode, we will honor any number you send to us as the outgoing CLI, as long as the number is either a valid YourCloudPBX number or ‘verified non-YourCloudPBX’ number.
