Hi,
When i have sip alg set to disabled, all my extensions work and the ONLY problem is that on hold issue.
-- Understood
when i enter the "set security alg sip retain-hold-resources" command with sip alg still disabled, the on hold issue remains.
-- This command would have no effect if the SIP alg is disabled.
when i delete the sip alg disable command, but leave the "set security alg sip retain-hold-resources" command, then reboot the phone, the on-hold issue is solved....but after a while when i try to call that extention, it does not ring.
-- It means that this command resolves the hold issue for you when the ALG is enabled.
--But it introduces new issue for you where the extension does not ring.
--This essentially means that the SIP ALG might not be working properly and you might be hitting the bug mentioned earlier by Pulkit.
Also, can you elaborate on what you mean by "opened all the ports for communication manually through security policies" please?
-- SIP ALG opens pinholes after inspecting SIP packets to allow the return communication. If your setup works without ALG, it means that you would have opened all the ports between the source/destination server manuall using security policies.
Suggestion would be to upgrade the SRX to a resolved version for that PR.
