[asterisk-users] Cisco SPA303 won't ring for more than 60 seconds

[Mike Diehl]

Hi all,

I've got a user with a couple of Cisco SPA303's.  When I dial their phones
with a dial string like:

dial(sip/phone-a,300,rwkxttT)

The phone rings, as expected.

However after exactly 60 seconds, I get:

[Aug 21 02:09:56]     -- Got SIP response 480 "Temporarily not available"
back from a.b.c.d:5062
[Aug 21 02:09:56]     -- SIP/phone-a-00006a9d is circuit-busy
[Aug 21 02:09:56]   == Everyone is busy/congested at this time (7:0/6/1)

Clearly I'm asking the phone to ring for 5 minutes, but it's giving up
after 1. Does anyone know how to fix this?

TIA,

Mike.
