Incoming (Dial-In)
This configuration is for dial-in, that is, calls from a telephone in the PSTN in to the conferencing service/platform
What follows are basic configuration requirements to support interoperability with iotum.
DTMF RFC2833 Only
Caller ID format: E.164 (ie 443307771307)
Please use E.164 format, even for NANPA numbers, in the To: of SIP INVITES, e.g. To: <sip:14165551212@137.184.201.74:5060>
Supported Codecs: G.722 (preferred), G.711U/G.711A
Required information from you for iotum to finalize configuration:
*email us at operations@iotum.com and pls cc cara@iotum.com )
The signaling IPs on your side, so we may whitelist them in our infrastructure;
The numbers you will be using in INVITEs’ To: so we may associate them with your white label instance.
Important notes about our signaling IPs
The values above are typical; however, select the one with the lowest latency for your primary, and the second-lowest for your secondary, from the following list:
161.35.253.199 (US east coast)
64.225.91.54 (US west coast)
143.244.204.70 (Frankfurt)
139.59.193.50 (Singapore)
139.59.48.42 (Bangalore)

Outgoing (Dial-Out)
This configuration is for dial-out, that is, calls from the conferencing service/platform out to a telephone in the PSTN. This is less common than Incoming/Dial-in (for which see its separate documentation).
What follows are basic configuration requirements to support interoperability with iotum.
DTMF RFC2833 Only
We will send From: and To: in INVITES as full E164 including the leading + (i.e. +443307771307)
Supported Codecs: G.722 (preferred), G.711U/G.711A
To avoid toll fraud and related issues, please configure trunks to either or both:
accept INVITES from us only from any of the IP addresses below;
require digest authentication (and, of course, generate and provide us credentials)
Please supply us with IP address[es] or FQDN[s] of outbound proxy[ies] and any special instructions about the order in which to try them, etc.
