Why Set at the SIP Level?
Setting the caller ID at the SIP level will be highest tier that a Caller ID can be set and will overwrite the caller ID set in the phone system. Caller IDs at the SIP Trunk level have a maximum of 15 characters. They also can be set on standard and enhanced numbers. Toll-free numbers can not be guaranteed to have a CNAM update in the SIPTrunk.com portal as there can be special steps needed.
Propagation Notice
