[cisco-voip] QSIG CallForwardAll between PBX-IP phones fails

[Ruben Montes]

Hello,

I have a CCM 4.1(3)SR2 cluster connected through a router 2851 with a
MGCP PRI QSIG with an Ericsson MD110.

If I have an IP phone forwarded to another IP phone, and I try to call
the first one from an analog phone that should go across the QSIG, call
rings for a second in the final phone and the hangs.

Any idea?
