[OpenSIPS-Users] Merged Request

[Toyima Dias]

Hello,

I've a doubt about a little problem in my opensips server, right now i just
have 2 softphones registered with my opensips server, every time i restart
the phones opensips creates the following:

OpenSIPS:/usr/src/opensips-1.6.3-tls#opensipsctl ul show

As you can see, user 1001 has created 2 registrations (don't now why, it
should sent an expires=0 when the softphone was restarted...it might be a
problem of the zoiper softphone?); the problem is when 1000 calls 1001,
Opensips send INVITE to both registrations of 1001 (the same equipment), and
this phone send a 482 Merged Request...i've been checking the section
8.2.2.2 at RFC 3261 but i'm quite confuse...what should i check?
