#groundwire — Public Fediverse posts

this is just cursed behaviour - whather #Groundwire registers when something else is using same external IP depends on what order SIP registrations arrive!

In this case its not a disaster as if I am on site I have far better devices available than my mobile phone to make SIP calls with (or can just use its LTE data), but its something worth being wary about as it could bite you in the arse if you are setting this up in somewhere where you don't have access to a different IP address to that shared by a #FreePBX inter-PBX #trunk

todays #VOIP discovery- - found another snakehead at the end of a #trunk - this time I am using #Acrobits #Groundwire #SIP client on #Android for a mobile extension on #cloud #PBX

Works *unless* I use a wifi connection with same external IP address as on-site PBX connected to cloud PBX (registered as PJSIP interPBX trunk and IP authentication).

When Groundwire extension tries to register as #endpoint on #FreePBX, #AOR records get all confused and #Groundwire shows "error"

tried adding external IP address to "Match (Permit)" in FreePBX extension entry - alas - this allows Groundwire to work but hoses outbound calls from the on-site PBX so had to be reverted (not a complete disaster as I can use the other wifi connection or LTE for Groundwire)
