[Asterisk-Users] Not call pickup for call to sip from mgcp phone

[Luis Vazquez]

Just by the way, do anybody knows if call pickup of a call to a sip 
extension from a mgcp phone is supposed to work (even if sip keeps ringing).
The scenary is as follows:
3 at mgcp02 (ext 136) calls sip/julia (ext 133) and after It starts ringing 
2 at mgcp02 (ext 135) dials *8.
Nothing happens, only 135 gets congestion tone, 133 keeps ringing and in 
the asterisk console I get:
    -- SIP/pbxip.net-5d2c is ringing
    -- Endpoint 'aaln/2 at mgcp02-1' observed 'hd'
    -- MGCP mgcp_new(MGCP/aaln/2 at mgcp02-1) created in state: Down
    -- Endpoint 'aaln/2 at mgcp02-1' observed '*'
    -- Endpoint 'aaln/2 at mgcp02-1' observed '8'
May 28 18:01:40 WARNING[1409052]: chan_mgcp.c:1857 mgcp_ss: No call 
pickup possible...
    -- Endpoint 'aaln/3 at mgcp02-1' observed 'hu'

All callgroup=2, pickupgroup=2 and call pickup works from mgcp to mgcp.
Asterisk version 0.9.0 (this is production system, til they kill us).

Any hints?
Thank's all.
