subscribePresence

Hi,

I can subscribe to one users presence fine, but when I try to do another subscribePresence to another sip, there is no response. eg

->{"api":"PbxApi","mt":"SubscribePresence","sip":"anette","num":null}' |

<-{"api":"PbxApi","mt":"SubscribePresenceResult"}

<-{"api":"PbxApi","mt":"PresenceState","up":true,"sip":"anette","dn":"Anette test","num":"3784","email":"anette@vcom.no"}

<-{"api":"PbxApi","mt":"PresenceUpdate","presence":[{"contact":"tel:","status":"open","activity":"dnd"},{"contact":"im:","status":"closed"}]}

->'{"api":"PbxApi","mt":"SubscribePresence","sip":"tomas","num":null}'

Any idea why?

Re: subscribePresence

Hi Tomas,

can you please try the following:

Omit the "num" attribute. In the text file I see that it's an empty string "" instead of null/undefined.
Add a "src" attribute to the two SubscribePresenceMessages with different string value.

{"api":"PbxApi","mt":"SubscribePresence","sip":"thomas","src":"1"}

{"api":"PbxApi","mt":"SubscribePresence","sip":"anette","src":"2"}

Please tell, if this helped. If so, I should clarify in the documentation.

Matthias

Re: subscribePresence

Hi Tomas,

I found a bug in our software that could be your problem.

For now you should be able to work around it by using a distinct "src" for each presence subscription.

Re: subscribePresence

Hi Matthias,

thanks.

Yes it works with an unique src for each subscription. So this is a bug and will not be required in future releases? You know when it will be fixed?

Regards
