Registration failed with domain

[mike99]

Hi,

I'm trying FusionPBX and my domain registration always fail with the following error:
[ERR] sofia_reg.c:2447 425b855e-1f5a-4c5a-b3eb-e23b2bb14ae8 Failed Registration with status DNS Error [503]. failure

I can't find anything with this error.

Phone register to the A record corresponding to the domaine so

a 43200 IN A 192.168.1.100
where 192.168.1.100 is my FusionPBX server

phone outbound proxy is
a.mydomain.com

Same setup on Freeswitch work fine so I'm a little confuse why it wouldn't work on FusionPBX.

If somebody could help me.

Thanks

That looks like an error to a gateway not phone.

Also, put the outbound proxy in as IP and server as domain name in phone.
