we’re running an asterisk 126.96.36.199 (debian-packages) on a new debian-squeeze box with FreePBX 2.9 with about 70 sip peers.
The peers are most Grandstreams GXP2010 and GXP2110 with heavy BLF-Usage. After update Asterisk-update from 1.4 I had to fiddle a lot to get BLF-Pickup for the GXP2010-Phones working again.
I needed to set pedantic=no, notifycid=ignore-context inside sip.conf. To set subscribecontext wasn’t needed and __PICKUPMARK has already been set by FreePBX as well.
After this was working sip becomes unavailable twice and I had to restart asterisk.
The last messages inside the log both times where
chan_sip.c: == Extension Changed YYY[ext-local] new state InUse&Ringing for Notify User XXX
After this I set notifyringing=no, notifyhold=no inside sip.conf and this didn’t happen again.
is it possible that sip-channel becomes unstable with heavy sip-notify/hint usage of GXP20XX-Phones inside asterisk 188.8.131.52 with activated notifyringing=yes notifyhold=yes settings ?
