In a SIP video call, the receiver of the video stream respond with the capabilities of its decoder.
The parameter which defines that is the profile-level-id. Here is an example value of the profile-level-id parameter: 428014
RFC 6184 defined that as
A base16 [7] (hexadecimal) representation of the following three bytes in the sequence parameter set NAL unit is specified in 1: 1) profile_idc, 2) a byte herein referred to as profile-iop, composed of the values of constraint_set0_flag, constraint_set1_flag, constraint_set2_flag, constraint_set3_flag, constraint_set4_flag, constraint_set5_flag, and reserved_zero_2bits in bit- significance order, starting from the most-significant bit, and 3) level_idc.
According to that, the following parameters from the example value can be identified:
How to relate those numbers to the profiles and levels defined for h264?
For such things you should read actual H.264 spec not Wikipedia. Using it you can parse your example as
So result is Constrained Baseline profile Level 2.0
