Background
Installation is in the cloud and is serving two (2) locations, about 20 minutes apart. Agency1 has 10 phones, Agency2 has 4 phones. Of those, 11 user phones are Sangoma S705 and 3 conference room phones are Sangoma S500.
Three users are alternating between the two locations. As such, they each have an S705 phone at each location and I have their phones configured with two accounts so that they can make/receive calls for either agency. This way their outgoing calls have caller ID for the appropriate agency. Inbound Routes with different Alert Info (distinctive ring) handles incoming calls.
UserA and UserB are primary to Agency1. UserC is primary to Agency2. As such, the phones are configured as follows: (Note the difference in phone number assignments for UserC)
Agency 1 - UserA
Extension 122 uses Account1 and Agency1 phone number 111-111-1111
Extension 322 uses Account2 and Agency2 phone number 222-222-2222
Agency 1 - UserB
Extension 133 uses Account1 and Agency1 phone number 111-111-1111
Extension 333 uses Account2 and Agency2 phone number 222-222-2222
Agency1 - UserC
Extension 125 uses Account1 and Agency2 phone number 222-222-2222
Extension 325 uses Account2 and Agency1 phone number 111-111-1111
Agency 2 - UserA
Extension 222 uses Account1 and Agency1 phone number 111-111-1111
Extension 422 uses Account2 and Agency2 phone number 222-222-2222
Agency 2 - UserB
Extension 233 uses Account1 and Agency1 phone number 111-111-1111
Extension 433 uses Account2 and Agency2 phone number 222-222-2222
Agency2 - UserC
Extension 225 uses Account1 and Agency2 phone number 222-222-2222
Extension 425 uses Account2 and Agency1 phone number 111-111-1111
Issue
I provided a lot of info to help you understand my dilemma. Everything has been working well until two days ago when the phone lines for Agency1 were inadvertently disconnected (thanx, AT&T). They were restored later that day. However, there were issues with those six phones.
Initially they were not registering. That was corrected. All phones at Agency1 are functioning properly. Two phones at Agency2 are functioning properly (UserB and the conference room). The quirky issue is with Agency2, UserA and UserC.
Both accounts on the phones for UserA and UserC are registered. However, calls made or received using Account1 have no audio. Calls made and received using Account2 are fine. Phones ring appropriately for incoming calls but, when answered, there is no audio if the phone number is using Account1. This is true for both incoming and outgoing calls whether the phone uses the speaker or the handset. Note that the phone numbers for UserA and UserC are reversed so it does not seem to be a phone number issue. And UserB is working fine.
Any ideas?
