Need help with asterisk patch for cisco video & plf

hi all ,

i have asterisk 11.11

i have cisco phones with sip flashed.

but i have two issues:
1-blf not working
2-video over cisco phones is not supported

can you guide me with the patch required to do this task ??

Ask your phone vendor not asterisk.

hi , thank you.

but i need it for 7970 iphones of cisco and it should work.

can you help ?

NO, thats a question for YOUR VENDOR, if your vendor can’t manage that then consider to use a phone that support SIP protocol like Yealink they are cheaper than Cisco and works much better with asterisk.

yes agree ,
but does asterisk who do the patch or the vendor ?
