[Freeswitch-users] R: Dial string issue for multiple registrations contact

Tue Sep 27 13:14:20 UTC 2022

Hi Brian,
thanks for your answer.

Anyway, there is something confusing us: arn't curly brackets supposed to be used for parameters common to all the dialed extensions?

In this scenario I have 2 extensions registered to 2 different devices (so 2 differente sip_contacts), and I'm trying to dial both with a bridge (answer group feature)
As dialed extensions are different, they also have different presence_id (not common for all registrations), so I can't put it into the curly brackets.

Here you are again the situation and the code:

{option1=value1, option2=value2}
[presence_id=1001 at domainA]${sofia_contact(user/1001 at domainA)},
[presence_id=1002 at domainA]${sofia_contact(user/1002 at domainA)}

suppose that users have both 2 active registrations, the desired dialstring should be:

{option1=value1, option2=value2}
[presence_id=1001 at domainA]sofia/internal/sip:1001 at 10.10.10.1,
[presence_id=1001 at domainA]sofia/internal/sip:1001 at 10.10.10.2,
[presence_id=1002 at domainA]sofia/internal/sip:1002 at 10.10.10.3,
[presence_id=1002 at domainA]sofia/internal/sip:1002 at 10.10.10.4

Since {sofia_contact(user/1001 at domainA)} is expanded in a list of comma separated values, what I get is: (spaces for readeability):

{option1=value1, option2=value2}
[presence_id=1001 at domainA]sofia/internal/sip:1001 at 10.10.10.1,
                                                                                               sofia/internal/sip:1001 at 10.10.10.2,
[presence_id=1002 at domainA]sofia/internal/sip:1002 at 10.10.10.3,
                                                                                                sofia/internal/sip:1002 at 10.10.10.4

so, only one registration per extensions gets the presence_id parameter.

Thanks
Francesco

Move presence_id into {} then they'll all get it.

hello to everyone,  I'm taking my first steps on this wonderful software!
I have a little problem:

in a lua script I'm forging a dialstring like this:
{option1=value1, option2=value2}[presence_id=1001 at domainA]${sofia_contact(user/1001 at domainA)},[presence_id=1002 at domainA]${sofia_contact(user/1002 at domainA)}

suppose that users have both 2 active registrations, the desired dialstring should be:

so, only one registration per extensions gets the presence_id parameter.

I also tried to manipulate the sintax adding parenthesis but it was not accpeted and errors returned.

Is it a way to achieve the desired dialstring?many thanks!
