I have setup a trunk from OVH. (pjsip)
Incoming calls are OK. A specific context was required: “from-pstn-toheader” to get the incoming CallerID.
Outgoing calls are going out, but…
I can not find any working configuration to get the outgoing CallerID to the destination phone.
I do have it working fine with other trunk providers.
OVH support made me change the supported codecs on their side ?? No change.
OVH support asked me to use a softphone to check. I did with Zoiper Pro on PC. No change.
