One question: you write "when I sign-in into IPTEL service". How do you
do this? Your local User Agent must register itself at siproxd. And as
siproxd currently does no support "proxy-chaining", your local User
Agent very likely does *not* register itself at IPTEL.
If you are using a sip<xxx>@iptel.org registration address, your
configuration is probably working 'just by accident'.


The following scenario is *not* supported by siproxd:

				  +-----------+
          :			  | registrar |
	  :			  |	      |
 	  :			  +-----------+
+-------+ : +--------+                  | iptel.org
| local | : |firewall|  Internet        |
|  UA   |---|siproxd |------------------+-------------//
+-------+ : +--------+

- siproxd will *not* register itself or the local UAs
  to an other registrar/proxy.



What *is* supported:
          :
+-------+ : +--------+ 
| local | : |firewall|  Internet   
|  UA   |---|siproxd |--------------------------------//
+-------+ : +--------+  myname.homeip.net

- UA registers itself at siproxd,
  using a registration record:
  sip:us...@my...

- myname.homeip.net must resolve to the
  public IP address of the firewall.
  (-> eg DynDNS service)

- Incomming Calls must be directed to
  sip:us...@my...


Maybe, some day siproxd may support the first situation as well, but
currrently is does not. I also don't know *when* I will have time
(and I'm in the mood for) to start working on such an issue.

I'm quite sure that the reason for you problem (not seeing your partner
online) is that your setup is similar to the first one.
(If IPTEL is tolerant and redirect calls *TO* you, voice calls may work.
 It could also be that making voice calls only work in one direction -
 eg only outgoing calls work but incomming calls fail)

I hope this helps.
