Router Settings for using SIP dialing

[Hortoristic]

I'm able to have SIP calls come in on SP2 – port 5061 – as 19142961111@mydomain.dyndns.info:5061 - been using for a couple years works great!

However when I configure SP3 for SIP, and dial 19142961111@mydomain.dyndns.info:5062 – I can only hear someone talking, they can't hear me.  

This feels like router port forwarding issues; so here are my settings; anyone see anything not right – which feels somewhat doubtful as I even have OBI in DMZ at moment?

Router Settings - All forwarding to my OBI local IP:
UDP 19305, 10000-11000, 16600-17098
TCP 5222-5223, 6800, 5060-5063

OBI Settings:
Voice Services > SP3 Service > Enabled: checked
Voice Services > SP3 Service > X_ServProvProfile: C
Voice Services > SP3 Service > X_RingProfile: B
Voice Services > SP3 Service > X_CodecProfile: B

My SIP settings using ITSP Profile C – all default except:
ITSP Profile C > SIP > ProxyServer: 127.0.0.1
ITSP Profile C > SIP > ProxyServerPort: 5061
ITSP Profile C > SIP > RegistrarServerPort: 5061
ITSP Profile C > SIP > OutboundProxyPort: 5061

I don't follow what you are doing, but I am wondering why ITSP Profile C would have 5061 port numbers, and you are calling 5062. I don't know...

Yes - this has been confusing for me also.

For the last couple years; when I dial: 19142961111@mydomain.dyndns.info:5061; it rings my SP2.  All my port settings say 5060; a nd not the 5061 you would think.  However; all talking is working fine.

It appears I don't need to change any of the 506x numbers on the OBI, 5060 seems to be sp1, 5061 is sp2, 5062 is sp3, and 5063 is sp4.

19142961123@some.dyndns.info:5063 seems to ring sp4 ok.
