Re: [SR-Users] Disabling DNS SRV records checks
Hello, I am not familiar with carrierroute and its internals, but I guess it sets either request uri ($ru) or dst uri ($du). Now, if the ruri is sip:u...@domain.com, then kamailio will do dsn srv to find out the target host port for sip service. If the ruri is sip:u...@domain.com:5060, then kamailio does only A/ query for domain.com (as per ietf rfc). Probably you can try the variant you mentioned to see if the $ru/$du is set accordingly -- I cannot help more with carrierroute in this regard.

Re: [SR-Users] Disabling DNS SRV records checks
Hi Daniel, I'm using table carrierroute with scan_prefix and rewrite_host fields to match routing from DIDs to my servers and rewrite_host is like sub.domain.com only. do you like to add the hosts there with sub.domain.com:5060 ? or what ?
