[asterisk-users] SIP reload not changing codecs

[Steve Edwards]

Asterisk 13.3.2

I change the allowed codec from ulaw to g729 in sip.conf and enter 'sip 
reload' on the console, but calls continue to use ulaw until restart.

Before reload:

lc10*CLI> sip show settings
Global Signalling Settings:
---------------------------
   Codecs:                 (ulaw)

lc10*CLI> core show channel SIP/poly-e637-00000000
   NativeFormats: (ulaw)
     WriteFormat: slin
      ReadFormat: ulaw

After reload:

lc10*CLI> sip show settings
Global Signalling Settings:
---------------------------
   Codecs:                 (g729)

lc10*CLI> core show channel SIP/poly-e637-00000001
   NativeFormats: (ulaw)
     WriteFormat: slin
      ReadFormat: ulaw

After restart:

lc10*CLI> sip show settings
Global Signalling Settings:
---------------------------
   Codecs:                 (g729)

lc10*CLI> core show channel SIP/poly-e637-00000000
   NativeFormats: (g729)
     WriteFormat: slin
      ReadFormat: g729

Why do I need to restart to get calls to actually use the new codec?
