[asterisk-users] Cisco SPA 5xx/3xx/9xx phones don't respond to SIPAddHeader(Call-Info: answer-after=0)

[Carlos Alvarez]

All other phones we work with will auto-answer when we do this:

[macro-paging1way]
exten => s,1,SIPAddHeader(Call-Info: answer-after=0)
exten => s,n,Page(${PAGINGLIST})
exten => s,n, Hangup

The SPA phones simply ring.  I have verified that Auto Answer Page is set
to yes (the default).  We've tried a variety of firmware versions and phone
ages, going back to an old 942 and new 504s.  Any ideas?
