Hi Klaus,

What do you mean with hairpin? AFAIK Cisco uses this term and means
"VoIP<->VoIP" calls in their gateways. Hairpin is also used in STUN
terminology and means that the NAT router forwards packets from inside1
to inside2 although the packets are addressed to the external socket of
inside2.
What does hairpin in asterisk terminology mean?

That's interesting. I tried to build up my private home pbx with a combination
of SER and ASTERISK. The result: The missing call routing capabilities which
* describes with the nice word "hairpin" makes it useless for PBX
architectures. ASTERISK might be useful for something especially because it
supports NT mode for ISDN, but I cannot see for what. Maybe you can help me a
little and tell me how to overcome this big "hairpin" issue. I would be very
thankful because that would allow me to set up a very nice PBX replacement
which was almost completed before I was stopped by the "hairpin". I can think of two application which might be
appealing.
The first one is a pbx which can be deployed in a company. All internal
calls are routed through it. One can distribute the central ser server
functions into multiple smaller ser servers.
I guess for PBX applications asterisk is better.
