Re: VVX 1500 (5.9.1) only shows BLF when ringing

Hello @bobjase ,


to bring this to a conclusion using a VVX1500 or a VVX 601 the BLF process outlined => here <= shows the BLF on a VVX 1500 (or VVX 601) as follows:


VVX_1500_Static_BLF_01.pngIdle state 



VVX_1500_Static_BLF_02.pngBusy or Alerting state

RFC 4662 support was added by Digium / Asterisk => here <=


Polycom addressed an issue in VOIP-119610 where a phone would crash SUBSCRIBING to a attendant.uri.


Support for RFC 4662 was added by Polycom back in 2009 via VOIP-42091 and focuses mainly on our Partner Broadsoft.


Any change to the above would require a feature request as explained in detail => here <= 

Best Regards
