In order to avoid this issue it could be nice to query a BD table looking for the "User-Agent" and just exec "pua_set_publish()" if the device doesn't support presence PUBLISH.
why cannot methods field of usrloc table be used?
I don't understand what you mean. "methods" field in "usrloc" table just means allowed receiving methods for that the device, but not which methods it can generate.
For example, Twinkle 1.1 that support presence sends this "Allow" header:
Allow: INVITE,ACK,BYE,CANCEL,OPTIONS,PRACK,REFER,NOTIFY,SUBSCRIBE,INFO,MESSAGE
And Linksys PAP2, that doesn't support presence, sends this one:
Allow: ACK, BYE, CANCEL, INFO, INVITE, NOTIFY, OPTIONS, REFER
Maybe devices which send PUBLISH allow always a received SUBSCRIBE, but having "SUBSCRIBE" in "Allow" header dones't mean supporting PUBLISH. Does it?
