[Serusers] re: i have a problem and i'm so desperate i'm offering money to anyone who can solve it

Hello all, I have a continuing problem with registering a grandstream BT102 to SER. It is behind a router but i am pretty sure NAT is not a problem because i got the phone to register to asterisk perfectly. The problem is this: 1. i cannot modify the SRV records on my server - it is set up with a DNS A record for "phone.myserver.com" 2. i can register x-lite to the server fine, by putting the IP address in the SIP proxy and outbound proxy fields, and using "phone.myserver.com" as the Domain/Realm. SER checks users against phone.myserver.com (digest authentication) and the grandstream doesn't register (which makes sense, because on the grandstream you can't set the domain/realm and the proxy server separately) however: according to the grandstream website: What if my SIP URI domain is different from the SIP proxy server FQDN (Fully Qualified Domain Name)? With firmware 1.0.3.60 and later, you can put the your SIP URI domain name into the SIP Server field, and put the actual sip server FQDN into Outbound Proxy field. The phone will use the domain name in SIP Server as part of SIP URI but send and receive SIP messages through the SIP proxy server defined in the Outbound Proxy field. -but that doesn't work, i still get 401 errors i am so desperate that i will give the first person who gives me information to solve this problem $20 of amazon credit (you can use it to get one of those spiffy new linksys PAP2 devices) as a token of appreciation. thanks, yair p.s. don't tell me to enable SRV. I know this would probably solve the problem, but it's not an option. if x-lite can register without SRV records i'm pretty sure the grandstream can as well, i just don't know how.
