Jan The ENUM policy never had LRQ support, it has always been only call signalling. The ENUM policy was disabled from incoming LRQ queries due to the possibility of infinite looping when using it with SRV so it is mow restricted to only doing ENUM lookups for locally registered users (via ARQ). The H323 URI, H323:user@host[:port] which is returned by the ENUM lookup is by default (according to H.323 Annex O) only a host address imply call signalling (on the specified TCP port, if omitted the default is 1720). >From H323 Annex O O.9 Resolving an H.323 URL to IP Address using DNS The host part of the H.323 URL can specify one of the following: - The IP numeric address of an H.323 entity. - The DNS name of a host which is an H.323 entity. (ie reach by Call Signalling) - The remote DNS domain containing H.323 SRV RRs. (ie handle by SRV policy ie _h323ls._udp record (LRQ)) Simon -----Original Message----- From: openh323gk-users-bounces@xxxxxxxxxxxxxxxxxxxxx [mailto:openh323gk-users-bounces@xxxxxxxxxxxxxxxxxxxxx]On Behalf Of Jan Willamowius Sent: Tuesday, 11 September 2007 6:11 AM To: openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Subject: Re: Problem with call setup using ENUM on GNUGK226 Hi Simon, can you please explain a bit more why GnuGk shouldn't rewrite the called alias in an LRQ via ENUM ? I see that you deactivated ENUM for LRQs earlier this year, but I'm not sure why this is neccessary.
