Dear FreePBX Community,
I’m configuring a SIP trunk with a provider using the Sipwise C5 platform, which supports serial and parallel call forking based on Q values in SIP registrations. I need to include a Q value in the SIP Contact header when registering FreePBX to this trunk.
What I Know:
- Q value (0 to 1.0) prioritizes devices in serial forking.
- Sipwise defaults to
q=-1
if no Q value is set.
Question:
How can I specify the Q value in FreePBX trunk settings (chan_sip or PJSIP)?
For more details on Q values and their usage, see the Sipwise documentation: Sipwise C5 Documentation – Call Forking.
Thanks for your help!
