[OpenSER-Devel] core_hash - reliability

[Carsten Bock]

Hi everybody,

i have a question regarding the core_hash-function from the
OpenSER-Core:
- how collision safe is the function? We currently use this function
over the Call-ID and with MAX_INT as Hash-Size to determine different
dialogs in our system; is it safe? If i read the SIP-RFC, i think i
should extend it to Call-ID and From / To-Tag...
- is there any (theoretical) chance, that dialog-matching of the dialog
module fails? (e.g. if two dialogs have a similar callid and tags?)

Thank you in advance,

Carsten
