Hi, I am looking into using in-dialog OPTIONs to implement a keep-alive mechanism for the MOH and park server. >From the RFC: 11.2 Processing of OPTIONS Request An OPTIONS request received within a dialog generates a 200 (OK) response that is identical to one constructed outside a dialog and does not have any impact on the dialog. This use of OPTIONS has limitations due to the differences in proxy handling of OPTIONS and INVITE requests. While a forked INVITE can result in multiple 200 (OK) responses being returned, a forked OPTIONS will only result in a single 200 (OK) response, since it is treated by proxies using the non-INVITE handling. See Section 16.7 for the normative details. I don't think this limitation affects us.. While using re-INVITEs would be ideal for keep-alives, most phones don't don't seem to support handling re-INVITEs from the MOH server. Does anyone have opinion against this method? Thanks, Arjun _______________________________________________ sipx-dev mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-dev Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-dev
