[OpenSIPS-Users] methods= from register contact

[Vlad Paiu]

Hello,

Upon registration, each UA can supply a list of allowed/supported methods.
OpenSIPS saves this information by using an integer, and bitmask flags.

The enum used is :
     enum request_method {
         METHOD_UNDEF=0,           /* 0 - --- */
         METHOD_INVITE=1,          /* 1 - 2^0 */
         METHOD_CANCEL=2,          /* 2 - 2^1 */
         METHOD_ACK=4,             /* 3 - 2^2 */
         METHOD_BYE=8,             /* 4 - 2^3 */
         METHOD_INFO=16,           /* 5 - 2^4 */
         METHOD_OPTIONS=32,        /* 6 - 2^5 */
         METHOD_UPDATE=64,         /* 7 - 2^6 */
         METHOD_REGISTER=128,      /* 8 - 2^7 */
         METHOD_MESSAGE=256,       /* 9 - 2^8 */
         METHOD_SUBSCRIBE=512,     /* 10 - 2^9 */
         METHOD_NOTIFY=1024,       /* 11 - 2^10 */
         METHOD_PRACK=2048,        /* 12 - 2^11 */
         METHOD_REFER=4096,        /* 13 - 2^12 */
         METHOD_PUBLISH=8192,      /* 14 - 2^13 */
         METHOD_OTHER=16384        /* 15 - 2^14 */
};

0x1F6F = 8047 = 4096 + 2048 + 1024 + 512 + 256 + 64 + 32 + 8 + 4 + 2 + 1 ,

Basically, using the methods integer and the above enumeration, you can 
tell what methods the registering UA supports.
