Can anyone help me with configuring BLF lines for extensions as well as parking lot for VoIP.ms? I’ve set up 3 sub-accounts (3 extensions) 610, 620, 630. These settings are manually provisioned, and extension to extension calling, and inbound and outbound calling is working fine. I want to use the additional soft keys to allow users to monitor the other 2 extensions, and 2 parking lot spots. Following the guide here, I opened a ticket with VoIP.ms and asked them to enable BLF on my account/server. They confirmed this is complete. According to this article, it looks like they turn on something called SIP Presence. Then it goes awry because it seems like the Grandstream phones do this differently than the Polys do.
I tried to enter the ‘address’ under the BLF Settings as XXXXXX_YYYYYY### where XXXXXX = VoIP.ms account number, YYYYYY = ClientCode, ### = 3 digit extension number. So for example it would look like 987654_WMTCHC610, which could be an account number and code for Walmart in Chicago for extension 610.
When I pop this into the phone configuration I get nothing new on the display, only the 2 registered extension lines. This includes when I put in their BLF code for the parking lots (this is in the Parking Lot section.) I reached out to VoIP.MS support for assistance and they aren’t sure and have no documentation on how to set this up. With other VoIP providers, I would put in the SIP username which is unique to each extension, like WMTCHC901_EXT_610 here and it works perfectly.
I read elsewhere that someone trying to get this working with Grandstream had issues until they changed to a different VoIP.ms server… I haven’t tried that yet but I will. I was just hoping to confirm someone’s working configuration before I tried that.
If anyone has cracked this with VoIP.ms and the Poly VVX phones, I’d appreciate you sharing your configuration. Thanks.
