We have a G3R V8 and a Philips Sopho 3070 switch connected with a Q-sig link. This appeared to work just fine for oevr half a year. Right now we have all sorts of small problems when trying to make calls from one switch to the other. Soem calls just give a busy tone, some make the connection but without sound and others get routed to the wrong extensions (only from g3r to sopho). When I look at the trunkstatus I can see that channel 16 is out of service, but all the other channels work (it's a 2 mb link). As far as I know nothing has been changed in either switch's config in the last few weeks.
Any ideas?
