Interesting to know that some devices still can't handle sip spirals...

Cheers,

Thanks Daniel

modparam("topoh", "mask_callid", 1)

It worked.

In the past I ran into other devices/PBXs that can't handle the fact
there is an outgoing/incoming call with the same callid. You could try
the topoh module (with modparam("topoh", "mask_callid", 1))

Beware that it might introduce other problems in some calls scenarios,
my prefered solution is to route the call to a b2bua (asterisk) when I
detected hairpinning.
