Dropped Calls - Priority warning

With newly installed system (Running FreePBX Version: 1.810.210.57-1) with just one SIP trunk setup occasionally calls are dropped and I get the following error:

[2012-03-21 15:21:19] NOTICE[20291]: pbx.c:4270 pbx_extension_helper: Cannot find extension context '' [2012-03-21 15:21:19] WARNING[20291]: pbx.c:10588 pbx_parseable_goto: Priority '' must be a number > 0, or valid label == Spawn extension (from-trunk, fax, 1) exited non-zero on 'SIP/link2voip-sw1-000000fe' -- Executing [[email protected]:1] Macro("SIP/link2voip-sw1-000000fe", "hangupcall,") in new stack -- Executing [[email protected]:1] GotoIf("SIP/link2voip-sw1-000000fe", "1?theend") in new stack -- Goto (macro-hangupcall,s,3)

Did you find any resolution to this? I’m going to keep searching but I’m encountering the same issues and have the same message. Was on a gotomeeting call and it dropped about 5 times in an hour on various time intervals.
