Your router appears to have a SIP ALG (sometimes called SIP Passthrough or similar) enabled.
If there is a setting to disable it, try that. Otherwise, we can look for a workaround after trying some simple measures.
- The two cases are presenting a different set of codecs. Try disabling all but alaw and ulaw.
- The pjsip case is sending a PAI header, which chan_sip does not. In the trunk, set Send RPID/PAI to No.
- Possibly a DNS issue. pjsip was sending the INVITE to 10.187.10.65. Was chan_sip sending to the same address?
If it’s not any of the above and you can’t easily disable the ALG, please describe your network setup: Modem/ONT make/model? Is it configured as a router? Separate router, if any?
My config:
Theres a modem(TP-LINK Archer XR500V) which receives fiber input. In that we register a vlan with connection type as DynamicIP. Then we bind that connection to a LAN port of modem, where the freepbx server connects.
I disabled SIP ALG.
Only allowed alaw and ulaw(in both extension phone(softphone) and in the freepbx), reloaded everyhting.
Still outbound calls reply with: “All circuits are busy”.

ALG is correctly disabled.
Please turn off Opus and GSM codecs for the trunk and also set Send RPID/PAI to No.
After Submit and Apply Config, turn pjsip logger back on and post a new log.
Still being rejected by the provider. Time to reach out and ask them why they kept sending 403 Forbidden’s on your outbound calls.
Sure, but the OP has a working chan_sip example, so I’m pretty sure that if we match that, it will fix the problem.
And if the provider can give a reason as to why it is being rejected we can also use that to figure out what is happening.
There’s nothing like a “provider reply”. They don’t know that much technical stuff, all they do is can give account credentials, change plans, etc.
I can provide any logs for you.
So, you got rid of the extra codecs and the PAI, but still getting a 403? If so, paste a new trace and we’ll try to spot another problem.
Then you should change providers. If your current provider can offer you no real support, you shouldn’t be with them.
The situation here is different, this is a normal sip connection offered(no charges, its free) to customers who have internet connection of BSNL.
I reached to a person who knows freepbx and BSNL, and he replied that BSNL dont work with pjsip.
But pjsip option is not there in freepbx17. What to do(apart from changing providers).
Fact: Here for just 200mbps plan, its costs only about $14, that too with free sip connection.
Not sure how that is possible. SIP is SIP and that is all PJSIP is, a SIP driver. It also is the driver for other SIP projects and applications. BSNL would have no clue it’s chan_pjsip in Asterisk.
So that person is wrong.

bro noel i am from telangana, and i am also trying since 25 days to get it working. at last found your post on broadband forum and tried chan sip. wow incoming calls work… but cant make outgoing calls.. can you kindly share your email id etc so that we can chat please.
If I understand correctly, you have a fully functional chan_sip setup, for which you posted a successful outbound trace.
Your last pjsip trace had two obvious differences (codecs and PAI) and I suggested that you correct them. Please post a current trace so we can see the responses and whether any differences remain.
Can you do outgoing calls with pjsip?
Screenshots(Black mask is the username/phone number of sip acc).
Also attached and recent logs during outgoing call.
Your provider is still rejecting the call.
@phanitheja
Can you do outgoing calls with pjsip?
yes finally cracked both incoming and outgoing calls.
