PJSIP calls not working

Asterisk Asterisk SIP
1

I don’t know if this has been answered before but I am new to the community and I need some guidance.

I do have my trunks setup in pjsip as below:

`; Trunks

[cloud]
type=endpoint
aors=cloud
disallow=all
allow=ulaw,alaw
context=from-cloud
direct_media=no
rewrite_contact=yes
rtp_symmetric=yes
transport=transport-udp
force_rport=yes

[cloud]
type=aor
qualify_frequency=60
contact=sip:x.x.x.x:5060

[cloud]
type=identify
endpoint=cloud
match=x.x.x.x

[cloud]
server_uri=sip:x.x.x.x:5060
client_uri=sip:x.x.x.x
retry_interval=60
transport=transport-udp

; Trunk to GSM Gateway
[gsm_endpoint]
type=endpoint
aors=gsm_aor
disallow=all
allow=ulaw,alaw
context=from-trunk
direct_media=no
transport=transport-udp
force_rport=no

[gsm_aor]
type=aor
qualify_frequency=60
contact=sip:192.168.90.3:5060

[gsm_identify]
type=identify
endpoint=gsm_endpoint
match=192.168.90.3

[gsm]
server_uri=sip:192.168.90.3:5060
client_uri=sip:192.168.90.3
retry_interval=60
transport=transport-udp`

But when i make calls, I get this response:

-- Executing [256778256xxx@from-cloud:1] NoOp("PJSIP/cloud-00000000", "Incoming call from cloud to 256778256xxx") in new stack

The call isn’t successful.

Anyone to look into this

This is not a valid Dial string for PJSIP. The correct format is:

PJSIP/256778256863@gsm_endpoint

Thanks for the prompt response. @jcolp

After modifying the Dial string, this is what i get.

That’s not the Dial string I gave.

You’re right, I’ve made the modification and now the call can go through.
