[asterisk-users] can PJSIP_MEDIA_OFFER work like SIP_CODEC?

[d tbsky]

hi:
   when using chan_sip, I can use set SIP_CODEC in dialplan to change
the codec of endpoint. this method didn't work with pjsip in asterisk
12/13.

   I found asterisk 12/13 has a new function PJSIP_MEDIA_OFFER.
according to the description, it seems can set codec, but the document
didn't offer any example. i try to use something like
PJSIP_MEDIA_OFFER(alaw)  but didn't work.

   can someone give an example for the function? thanks for the help.

Regards,
