37.5 Querying Device Channel Resources using SIP
OPTIONS
The device reports its maximum and available channel resources in SIP 200 OK responses
upon receipt of SIP OPTIONS messages. The device sends this information in the SIP X-
Resources header with the following parameters:

telchs: Specifies the total telephone channels and the number of free (available)
telephone channels.

mediachs: Not applicable.
Below is an example of the X-Resources:
X-Resources: telchs= 8/4;mediachs=0/0
In the example above, "telchs" specifies the number of available channels and the number
of occupied channels (4 channels are occupied and 8 channels are available).
